Blog from February, 2011

The CampusNet application is not available since ~21:20 Sat 26 Feb 2011.

This can be expected to last until Monday, 28.02.2011.

Update Sun 27 Feb 2011

CampusNet back up online since ~15:00 Sun 27 Feb 2011.

On Thursday 24 February 2011 between 07:00 and 08:00 local Bremen time servers and network components will be updated.

Server and network operations will be unreliable. Expect unavailable servers and sudden downtimes of services without prior explicit announcement.

If you have to work on files stored on the server during that time, then before the maintenance hour copy the respective files to your local hard disk, work on it locally, and after finishing your work and after the end of the maintenance interval, copy them back onto the server.

For more details on the maintenance hours see the Maintenance Hours page.

Due to the implementation of a new printing system (see email announcement by AVP M. Janke as of Feb 22, 2011), the Toshiba network printers will be upgraded during the next days.

The upgrade process will lead to temporary unavailability of the devices for printing and copying.

After the devices have been upgraded, new means of printing are required. Please see
Introduction of JACOBS network printing and scanning for further details.

This change will obsolete and supersede the previous admin and faculty print servers, which will be retired after the upgrade.

You can follow the upgrade "live" on this blog post during the deployment.

Overview

All Jacobs University Members and Jacobs University Visitors have access to printers shared over the network. The print queue is available within the Jacobs network and accessible by "any" computer.

Prints can be retrieved from any Jacobs networked printer on campus by using the appropriate CampusCard. Printout starts only after inserting the CampusCard into a printer terminal ("follow me printing"), allowing flexibility in time and location of retrieval, while preserving confidentiality of printouts and reducing unnecessary prints.

Use discretion in naming your files and print jobs, as this information is potentially public to anyone!

In addition, all Jacobs University Members can use the scanning feature of the network "printers" for free.

An FAQ is available at FAQ JACOBS network printing and scanning.

This printing and scanning system will supersede the previous admin and faculty print servers.

Printing for Yourself

Windows

To setup Jacobs network printing, first follow the guide How to configure Jacobs network printing on Windows once.

If you are working on a Jacobs domain computer, you need to be logged in with your Jacobs user account.

If instead you are working on any other Windows computer, you need to authenticate yourself with your JACOBS user account upon connecting to the print server!

Mac OS X 10.6 Snow Leopard

(warning) The information given for Mac OS X is complimentary and shared with best intent and knowledge. There is no support for Mac computers at Jacobs by IRC-IT!

To setup network printing, first follow the guide How to configure Jacobs network printing on Mac once.

To be able to retrieve your printout later, you need to be logged in to your Mac computer using an account named exactly as your Jacobs user account aka CampusNet account, or you need to configure your system to present your Jacobs user account to the print server, while printing.

For additional information on printing with Mac OS X Snow Leopard, see Apple's page Mac OS X v10.6: Mac 101 - Printing.

Linux openSUSE

(warning) The information given for Linux is complimentary and shared with best intent and knowledge. There is no support for Linux computers at Jacobs by IRC-IT!

To setup network printing, first follow the guide How to configure Jacobs network printing on Linux once.

To be able to retrieve your printout later, you need to be logged in to your Linux computer using an account named exactly as your Jacobs user account aka CampusNet account, or you need to configure your system to present your Jacobs user account to the print server, while printing.

Printing for Others

If you want the print output to be retrieved with a different card (e.g., by an assistant, or if your local computer account does not match your CampusNet user account), you'll need to use a special software. The software is available for Windows, Mac OS X, and Linux. The software will install a local print queue Qpilot_Konica on your computer. Printing into that local queue will open up the Qpilot application, which asks for a card number before sending the document on to the print server.

See How to install the Qpilot software for Jacobs network printing for installation instructions, and How to use the Qpilot software for Jacobs network printing for help regarding printing with that software.

Retrieving the Paper

To retrieve the paper, go to any Jacobs network printer, enter the appropriate CampusCard into the attached card reader and follow the displayed instructions to get the printout. For additional information using the card reader, see How to operate the CampusCard terminal for Jacobs network printing.

(warning) The number of the CampusCard used to retrieve the print output must correspond to the card number specified during printing, either implicitly by being associated to the user account used for printing, or explicitly by being entered in the Qpilot client software upon submitting the print job!

Printing Costs

Costs are deducted from the CampusCard used upon retrieval of the printout.

Printing is free for business use by employees (i.e., called "official" on the CampusCard reader display), all other use must be paid for.

In February 2011, prices per page for printouts and copies were set as follows:

Paper Size

Color

Price in Cent

DIN A4

b&w

Scans are free, i.e. need not be paid for.

Additional Printing Information

All printers within the Jacobs network printing option are of the same type: Konica Minolta Bizhub C552, with finishers FS-527 PK-517 (2-hole). They support duplex printing, stapling (only upper left corner for portrait documents), and 2-hole punching.

Output jobs, printed or unprinted, and scanned documents, retrieved or not, will be automatically removed from the server after three days.

If a printout is required, please use duplex and black&white printing whenever possible.

Please print responsibly. Mind the costs and the environment!

Scanning

The networked printers can also be used for document scanning. Scanning requires use of a personalized campus card, i.e. scanning with guest cards is not possible.

After inserting the CampusCard, select button "Copying" on the card terminal. Put your paper source on the copier, but do not hit the "Copy" button. Instead, above the printer's display, select the "Scan" function button, then on the printer display/touchpad tick the "Scan to Email" entry. An address book shows up: use the first and only address listed. Do not change any of the displayed information, especially do not change the displayed email address, and do not add another address (e.g., yours) - it won't work.

If you are using the paper feed for providing the scan input, after scanning all sheets the scan ends automatically. If you are using the glass surface for providing the scan input manually, after you scanned the last page you need to hit "Finish Scan" on the touchpad of the printer to end the scan job. The CampusCard needs to stay in the card reader until after the scanned document has been sent out by the printer.

After ending the scan job, an email is sent to the email address of the user account associated with the campus card used for scanning. The email contains a link with username and password to download the scanned file. Scanned files are purged after three days from the server.

Password not accepted?

Better use CTRL + C (STRG + C) and CTRL + V (STRG + V) to copy and paste the password instead right click "copy" and "paste" using the mouse

See How to operate the CampusCard terminal for scanning for more details.

Scans are free, i.e. need not be paid for.

Please scan responsibly. Mind any copyright!

FAQ

Please see FAQ JACOBS network printing and scanning.

Known Issues

  • The Qpilot software client lists all prints as "Color: No", and gives a sum of costs of 0 EUR.
  • The only possible destination email address upon scanning still needs to be selected from the address book of the copier.
Table of Contents

General

What is JACOBS network printing?

This is a centrally provided printing service. Every Jacobs University member and also guests can use various print stations on campus to print via Jacobs' network.

Why has it been introduced?

To enhance functionality for Jacobs' members, to save costs and to offer cost-saving and environemtally friendly print and scan functionality for "everyone".

What are the benefits of the new solution?

  • Everyone can print, including students and guests
  • Professional print quality for students is added
  • Printers in the colleges enhance availability for students
  • Security and privacy of printouts is enhanced by only printing upon retrieval
  • Costs can be reported and calculated
  • Unnecessary printouts are reduced, thus environmental responsibility is promoted
  • Private printouts for low prices are possible
  • Scanning is available for every Jacobs University member

Who has decided on this change?

This change was decided upon by the Academic Council on December 14, 2010.

What feedback channels exist?

  • If you would like to comment on the decision, please contact your liaision to the Academic Council.
  • If you have issues with administrative aspects (e.g., costs, accounting, CampusCard billing), please contact the purchasing department.
  • If your account data is missing information or is wrong, please contact the appropriate department maintaining your account. See Simple people search at Jacobs for more information.
  • If you have technical issues, please contact Service Desk for Faculty and Staff.
  • If you would like to praise the decision or features, all of the above will most likely be happy to receive feedback (smile)

Printing General

Can students print, too?

Yes. Undergraduates and graduates and PhD and "everyone" else.

Can guests of the university print, too?

If the guest has a Jacobs user account, he or she is actually a Jacobs University guest, hence also Jacobs University member and can use the facilities as described.

If the guest has no Jacobs user account, she or he is a Jacobs University visitor and can print by getting a guest CampusCard, or, if the guest is directly associated with a department, by using the Qpilot print software to print onto a CampusCard of the department.

Can Jacobs network printing be used from a Mac or Linux computer?

Despite Mac and Linux is not supported by Service Desk for Faculty and Staff, printing is known to work from these platforms.

Please read Introduction of JACOBS network printing and scanning to see details for printing from Mac and Linux.

Can Jacobs network printing be used from a private Windows computer or a Windows computer NOT being part of the Jacobs computer domain?

Yes! Please read Introduction of JACOBS network printing and scanning to see details for printing from non-domain Windows computers.

How is Jacobs network printing accounted?

Jacobs University employees upon retrieving the print job can specify, if the printout is for business purposes or private purposes. Printing for business purposes is attributed to the employee's cost center. Printing for private purposes is to be paid from the CampusCard money.

Why is Jacobs network printing so expensive?

Compared to prices outside Jacobs campus, Jacobs' network printing prices appear to be a bargain.

Why is there no "private" option upon printout?

The option only appears, if the CampusCard has money on it.

Why is there no "printing" option upon using the CampusCard terminal?

The option appears only if there are print jobs awaiting printout associated with the CampusCard used at the card terminal.

Printing Features

What features do the printers support?

The central printers support color, duplex, top-left and two-left stapling, and 2-hole punching. They can print on DIN A4 and DIN A3 paper sizes.

They do not support other stapling modes.

Scanning is also enabled for Jacobs University members, free of costs.

Is the Qpilot print software required to print?

Most likely not, depending on the use case. See the following questions.

How can be printed without using the Qpilot print software?

Use the print server \\sprint01.jacobs-university.de, connect using your Jacobs account, and print to the QPilotKonica queue. Please read Introduction of JACOBS network printing and scanning to see details.

When is the Qpilot print software needed?

Only if you don't want your own CampusCard to retrieve the printout, i.e. if you want to "print for someone else". Or, if you can't or won't change the username the print system on your computer uses to contact the print server.

Where is the Qpilot print software?

Please see Introduction of JACOBS network printing and scanning.

Where is the print server?

Make sure you are printing from within the Jacobs network, e.g. by using VPN access.

Note: This actually allows to send a printout to the queue while away from campus. This might come in handy if you want the printout to be retrieved by someone else.

If you are using WLAN for printing, you need to have passed authentication, either via VPN access or using the "Unsecure Internet" login.

What might hinder an employee to print for business purposes?

Most likely, the employee's account data is missing a cost center. First search the account in the simple people search at Jacobs. If there is no cost center entry for the Jacobs user account, but there should, then please contact the personnel department to have it added.

Aborting a running print job still prints several more pages!

This can not be avoided.

If you feel you need proof printing before the full printout, consider splitting up your print into two jobs: one smaller portion at the beginning, and the larger rest of the document in a second job. Then, only retrieve the second print job if the first looks as expected.

Why is printout so slow?

The servers are fast, and the network is fast. The printers probably aren't. The speed appears okay for normal and medium size output. It appears somewhat slow for longer or complicated documents, and upon duplexing. Please plan ahead accordingly.

In a test, an 88 page black and white, moderately complex PDF took about 3:40 to printout duplexed, i.e. both sided. That's about 2.6 seconds per page, or 23 pages per minute.

For high-volume printouts you should conisder using the print service of Pulse Copy Shop.

Why is black and white accounted as color?

The printer accounts on a per-page basis. If 20 pages are printed, whereof 18 are black-and-white only, and 2 are color, the accounting is accordingly: 18 b&w, 2 color. See also the next question.

Why is a black and white page still accounted as color?

Please note that a single non-black dot on a page is enough to classify as color output. This might be the blue line below the document title, or the Jacobs logo on top, or a colored link in the document text, or the email sender's colored signature at the bottom, or the green "save the trees" icon.

If you want to be sure to get black and white output, set the printer properties and printout parameters upon printing to black and white only.

How do I delete a print job from the queue?

You can't. This is by design. To remove the print job from the queue, either use the cash terminal at one of the printers, or wait a few days until the job is automatically deleted from the queue.

How long does the print job stay in the queue?

Three days, so that it is possible to print into the queue on a Friday afternoon and retrieve the printout on Monday morning.

Note that, after establishing VPN access you can also print to the queue while off campus and retrieve the paper when you are back on campus, as long as it is within three days.

The Qpilot client lists all costs as 0, but still the sum is greater 0!

This is a current issue with the Qpilot print client. Just ignore any costs given by the Qpilot client. Only the printer "knows" what type of page it prints and how much it costs.

Everyone can see my print jobs if they know my CampusCard number!

Yes, this is by design. Please be sure to use inconspicuous and privacy conserving document and job names.

Everyone can print on my CampusCard if they know my CampusCard number!

Yes, this is by design. This enables group co-operation and cost sharing. Costs are only attributed upon paper retrieval. Not retrieving printouts will not cost money.

Someone is spamming my CampusCard with print jobs!

Hopefully, it is in error. If not, it is a clear violation of the General Policy Governing the Appropriate Use of Computer Resources. Please contact Service Desk for Faculty and Staff.

Scanning

What features do the scanners support?

Default scanning options are 300dpi in color to pdf. Output format can be changed to tiff, jpg, xps. There are technical restrictions with some combinations, e.g. a multi-page jpg is not possible. The document feeder or the glass surface can be used to provide the scan input.

Why is a scanned document not sent to the Jacobs email address?

To prevent flooding the Jacobs email server with large documents and (ab)using the email server as a document archive.

Why is the scan job suddenly terminated and no document is being sent?

As scanning is cost-free, there is no communication between the MFP/scanner and the cash card terminal during scanning. The cash card terminal has a timeout value for ejecting a "forgotten" card. If the timeout for "no communication with MFP" is reached, the card is ejected, the MFP/scanner is aborting all activitiy, and deletes all interim data.

The timeout is currently (May 2011) set to 30 minutes.

A detailed or long scan job is not sent?

The scan document size is limited to 30MB by the MFP/scanner. If the scan product exceeds this size, the scan is aborted and no document is sent.

To circumvent this limitation you can reduce the number of pages scanned or the quality of the scan.

How are the scanned documents secured?

Scanned documents are stored on a separate server. They can only be retrieved by providing a password sent by email to the account associated with the CampusCard used for scanning. The download is done via https.

The documents are removed from the server automatically after three days, retrieved or not. Documents can only be retrieved while connected to the campus network, either on site or via VPN access.

How can the scanned documents be removed from the server?

They can't, but will be automatically deleted after three days.

Can the scanned documents be searched for text?

No, the scanning process does not include OCR.

Tip: Microsoft OneNote, included in Office Professional, has an OCR engine and will find text in "unsearchable" PDF documents.

Why can guests print but not scan?

Printing with a guest card requires money on the card, which can be charged onto it with the cash station at the porter's gate. Though scanning is free, it requires an email address associated with the CampusCard. As guests (rather: Jacobs University visitors) are anonymous to the university, there is no email address available.

Note: To discuss this issue it is important to refine the meaning of the word "guest": long term "guests" are Jacobs University Guests and have a CampusNet account with a personalized CampusCard, hence are not considered "guest" in the CampusCard sense, but instead are Jacobs University members, and can use all the facilities including scanning as described. "guests" without any formalized affiliation with Jacobs University are termed Jacobs University visitor, will use an anonymous "guest" CampusCard from the porter's cash station, and will not be able to scan due to the missing email address association to the anonymous CampusCard.

IRC-IT is presenting at the iX CeBIT Forum 2011 of the Heise Verlag at CeBIT 2011.

The talk will be held (in German) on Thursday March 3rd, 13:30, at Hall 3, Booth E08, on the topic "Erfahrungsbericht Project IT Infrastructure Development" in the storage/infrastructure track.

Free day tickets

Here was a list of registration codes for a free day ticket to CeBIT 2011.

Data migration from the admin05 server (aka "the admin server") to the Jacobs shared network drive J: has been completed. Sharing of data by the server admin05 will be retired soon.

Finally, about two years after beginning the domain consolidation (see the announcement of 2009), the Windows domain GRADUATESTUDENT has been retired.

Login to that domain is no longer available, nor are resources. Please use the JACOBS domain instead.

In the morning of February 28, 2011, Jacobs University will change its landline telephony provider. This should not affect outgoing calls, but incoming calls to the University might not come through for a few minutes, depending on how smooth the transition will happen.

For privacy reasons, the matriculation number has been removed from the attributes maintained in Jacobs' account directory.

The new version of the "Simple people search at Jacobs" at https://ircitweb.irc-it.jacobs-university.de/ldap-search.php now displays pictures alongside the search results (if not unpublished).
