How can I cancel a build up of prints? when I press print it spews out a back log

While your question is not quite clear, I will provide a couple of suggestions. Usually when you press the cancel button, it pauses the printer and then you must use the arrow keys to select cancel job and then press the checkmark. Also check any computers to make sure that they do not have a job in their print queue. If the printer does not send back a job complete command, sometimes the computer will keep resending the job. Failing all else, restart your computer and your printer. Are the pages that are printing gibberish or is it the correct print job? If gibberish, you might have a corrupted print driver or the file you are printing might be corrupted.

If the light flashing is the "light bulb like button" or the "Ready/Light" button, it means that either the printer is:

• The printer is busy receiving and processing data or printing.
• The printer is printing a directory, font list, menu settings pages, or Print Quality Test Pages.


If it's Busy:
• Wait for the message to clear.
• Press and release Cancel to cancel the print job.
• Press and hold Cancel to reset the printer.


If it's printing a directory, a font list, menu settings pages, or Print Quality Test Pages:
• Wait for the pages to print. The Busy message is displayed as the pages print. The Ready light is on when the
printing stops.
• Press and release Cancel to cancel printing.
• Press and hold Cancel to reset the printer.

Who normally looks after your IT / printers as it would be best to contact them. However if you want to sort it out, depending on the local setup, you will need to e.g. on Windows log onto the print server and delete all the jobs from the Devices and Printers dialog. On UNIX you would type something like sudo cancel printername. We would need more information to successfully fix the problem.

Press the [PRINT MONITOR] key in the lower right corner of display. If fascimile option is also installed, it would say [SYSTEM MONITOR] key in same location. Anyways, after in print monitor screen, select the job that you want to cancel and press [CANCEL] key. Press [YES] to cancel. Press [DONE]. You might want to pull out all of the paper trays so the machine can't print while cancelling documents. Let me know.

After replacing the ink cartridge you should print the alignment page to work product perfectly.
Follow the below instructions to print alignment page:

1. Turn on the HP PSC 1200 or 1300 series product.
2. Disconnect the USB cable from the all-in-one.
3. Press the sequence of front panel buttons below to start the print cartridge alignment process. The button-press sequence must be completed within ten seconds. It might take several tries to complete the sequence within ten seconds.
   1. Press and hold Cancel .
   2. While holding Cancel , press On .
   3. When the Check Paper and Check Print Cartridge lights begin to blink simultaneously, release both buttons.
   4. Press Cancel again.
   5. Press Copies .
   6. Press Paper Type .
   7. Press Color Start Copy . The alignment page will begin printing. If the alignment page does not print, repeat the button-press sequence in this step.
4. When the alignment page has printed, place the page face down on the scanner glass and press Scan . The alignment is complete when the On light stops blinking.
5. Reconnect the USB cable.
   
   
   

If the issue still persists, perform semifull reset by following the below instructions

1. Unplug the power cord from the wall outlet.
2. Unplug the power cord from the back of the all-in-one.
3. Wait 30 seconds and plug the power cord back into the wall outlet.
4. Plug the power cord to the back of the all-in-one.
5. When the lights begin to flash, press and hold the On/Resume and Number of Copies Buttons.
6. When only the On/Resume light is flashing, release the buttons.
7. When the On/Resume light is steady, the reset is complete.

If the memory becomes full while the document is being scanned,
MEMORY IS FULL will appear in the display.
♦ Press the START/MEMORY key if you want to transmit the pages
which have been stored up to that point in memory. The remaining
pages will be ejected from the feeder. After transmission, the memory
will be cleared and you can transmit the remaining pages. You
will also need to transmit the page which was being scanned when
the memory filled up.
♦ Press the STOP key if you want to cancel the entire transmission.

Hope this helps. : )

Sounds like the printer spool is frozen.

Assuming you're using WinXP and logged in as an administrator (or with admin permissions)

START
Control Panel
Administrative Tools
Services

Locate the "Print Spooler"
Right click on this and choose "restart"

This will restart the print queue and will probably try to print the job again or delete it properly. If it tries to restart, just right click on the printer job and choose cancel again..

You may need to repeat but that should at least get you back up and running with other print jobs again.
