Technical information

printer mode'....print jobs may then be executed from the computer (only): To confirm if your printer

supports this feature, please refer to your printer user guide. This may also help you determine which

cartridge is causing the issue.

PRINTER TESTS / DIAGNOSTICS:

A. Clean cartridge/printer electrical contacts. Also inspect printer's internal carriage flex cables for

surface damage (i.e. burn marks) or an uneven contact surface (by which the cartridge's rear

electrical contacts mates with).

B. Perform either of the ‘B’ procedures below as steps vary by printer model:

B.1. Diagnostic Self-Test Page: [SELECT PRINTER MODELS]

1. Press the Setup Button located on the bottom center of the control panel, beneath the LED

readout.

2. Press 2 to select “Print Reports”

3. Press 6 to select “Self-Test Report” on the number keypad

4. Examine the resulting self-test page that prints. There should be lines extending all the way

across the page in black, yellow, cyan and magenta. A missing black line indicates a problem

with the black or photo cartridge. Faded, streaked or missing lines in the other colors indicates a

problem with the color ink cartridge. Refer to video at link below to help evaluate test pattern.

--- Providing the color cartridge is partially functioning, the diagnostic test print will be printed (this is a forced

service print test which is mainly used for the evaluation of ink cartridge electrical health). A good HP 56 black

cartridge should display 416 good nozzles (26x16 grid), while a good HP 57/58 color ink cartridge should show 300

good nozzles (10x10 color grid). For reference, please refer to video at link below to help evaluate test pattern :

B.2. Deskjet D1300, D1400, D2300, F300 series printers (HP 21/22 Cartridges)

Printer self-test:

1. Turn the printer on.

2. Press and hold down the Power button.

3. While holding down the Power button, open and shut the lid of the printer four times.

4. Release the Power button. The self-test prints.

5. Review test pattern; ensure all colors are firing. A missing horizontal line within the nozzle stair

step pattern indicates a misfiring ink nozzle. Perform cartridge cleaning to correct.

NOTE: When running the test on an HP Deskjet D2300/D2400 series printer it may be

helpful to use a pen or pencil to hold down the Power button.
