The print queue screen displays various kinds of information about the print jobs listed in the print queue. It can indicate whether the queue is working or not (in the blue title bar of the screen). It can report the status of each print job (spooled, printing, deleting, or error messages). It also lists the owner, the number of pages, and the size of each print job. The sections below tell how to check the status of a print job and how to clear jobs from the print queue when print job(s) may be "stuck."

Check status of the print job

If a particular printer is having problems, the first thing to check is the status of the print job, which may indicate the cause of the problem. Write down the status message so as to report it accurately. Many of the print queue error messages under the Status column are described in the last section of this document, COMMON PRINTER PROBLEMS. Look up the error messages in that section for suggestions in solving the problem.

To check the status of a print job:

Click the Start button, then Settings, then Printers.Find and double-click the desired printer name listed in the Printers screen.The print queue screen will appear with the currently printing print job at the top of list and allpending print jobs listed below it.Look at the top print job's status message. (You may have to drag the column separator to the right to see all of it).

Check the printer's status via the Web

Most printers serve their own web pages and can be checked for information, such as: printing status, display messages, toner cartridge usage, paper counts, paper tray sizes, and printer capabilities.

To find this information for one of the newer printers via the web:

Find the printer's IP address or name by following instructions in section FIND PRINTER DOMAIN NAME/IP ADDRESS AND PRINTER MODEL. When checking a specific printer on the web, you must enter the individual name of the printer you are checking.A web page will appear displaying status information.

Cancel or Purge print jobs in queue

Usually the top print job (currently printing) is the culprit causing the problem, so try canceling it first if dealing with a departmental printer. However, you may have to eventually delete (purge) all the print jobs in the list to get the printer to print again. HelpLine staff should purge all public print queues to clear out any old abandoned print requests that may still be waiting to print.

The Cancel command is used to delete a single print job, while the Purge command is used to clear all jobs from the queue. Note: Generally most users have permissions set to cancel only their own print jobs and no one else's. The Purge option is available only to users with special privileges, such as the Helpline staff, the LBIS staff, or certain individuals who manage the printers for their department.

Instructions for clearing print jobs from the queue:

Pause the print queue:In the print queue screen click Printer in the menu bar.Click Pause Printing (a checkmark will appear before Pause Printing).

Cancel a single print job (usually the top print document) in the queue:Highlight the top print job in the list.Click Document, then Cancel (this cancels only the one highlighted document).If you cannot get the top print job to disappear, you may have to recycle the printer once or twice to clear the memory of the printer completely. (See instructions in next section RECYCLE THE PRINTER).

OR:Purge all print jobs in the queue: (requires special privileges)Click Printer, then Purge Print Documents.The entire list of print jobs should disappear.

Unpause (restart) the print queue:(Remember to unpause the queue or the job won't print!!)Click Printer, then Pause Printing (checkmark now disappears from Pause Printing option)Exit print queue screen.

Try printing a second time.

Recycle the Printer in canon printer

If the print job will not disappear in the print queue list after deleting, try recycling the printer. This should clear the memory of the printer and will usually enable the printer to print again. It may also clear out any pending print jobs in the list as well.

Note: Sometimes the printer may have to be recycled a second time before it will print (if the top print job in the queue will not disappear with the first recycling).

To recycle the printer:

Turn off the printer power switch.If your printer has a little white print server (Lantronix) box attached on the back, unplug theblack power cord and the blue network cable that are plugged into that box. If there is no little white box attached, there will only be a blue network cable that must be unplugged.Wait 30 seconds and then plug the blue network cable (and the black power cord, if there is one) back into place.Turn on printer again and wait at least 5 minutes before printing a test page to it. It may take that long before print jobs will go through again successfully (See instructions in sectionPRINT TEST PAGE REMOTELY TO VALIDATE NETWORK CONNECTION).
