Factory reset Printer prints very slowly and wont print crossword grids

This type of problem is typically caused by one of the ink cartridges which is suffering from marginal electrical performance - either the HP92 (black) or HP93 (color) ink cartridge.

Can you perform the 'Self Test Page' test (see below). If this test is successful then this demonstrates the printer is 'generally operational', but if normal printing is still not permitted then either the HP92 (black) or HP93 (color) ink cartridge is likely electrically damaged and may need to be replaced*.

Perform Self Test Page:
1. Press and hold the CANCEL button.
2. Press the COLOR COPY button. Release both buttons.
3. The self test prints. The printed pattern will verify printer is generally functional. Inspect color bars to verify proper nozzle/jetting health.

-- Inspect printed nozzle stair step patterns - verify all ink nozzles are properly firing. Generally, if the Self Test Page prints ok then the printer is functioning correctly and the problem is with the ink cartridges - replace the suspect ink cartridge and retest. Refer to 2nd video procedure at the following link on how to read the Self Test page test (NOTE: HP74/75 cartridges are electrically identical to the HP92 thru 98 cartridges).

*Many cartridges eventually do encounter problems or failures. Severe cartridge errors are primarily caused by an electrical breakdown at the cartridge's nozzle plate. Ink *********** or corrosion into the nozzle plate will cause a failure of the tiny micro-electronics resulting in a variety of different error messages being displayed - see picture at bottom of this page: http://inkjet411.com/?page_id=1216

It is suggested to install a new HP92 and/or HP93 ink cartridge in it to resolve the current issue.
