Hp officejet 4315 is stuck in mfg mode. what can I do to fix this

Regarding your query, it sounds like the HP Officejet 4315 printer is locked into the advanced service test mode (i.e. one of your ink cartridges is causing the issue). Remove both ink cartridges and clean thoroughly before proceeding to next step - our Inkjet411 support links are provided below to help you diagnose the issue.

1) 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).

2) Perform either of the 'B' procedures below to verify HP Officejet 4315 printer and ink cartridge electrical performance.

B.1. Perform Tap 43 test: [for most older HP Officejet printer models with keypads]

1. Press * and # keys at same time
2. Enter 1234 (or 124). The 'Underware' menu should be displayed.
3. Using left/right arrow keys, navigate to Special Reports/Reports Menu (......or 'System Menu' / 'Information Menu' if Reports Menu is not available). Select Enter.
4. Using left/right arrow keys, navigate to 'Extended Self Test'.
5. Select Enter to print test print - evaluate test print. If excessive nozzles are missing from the stair step pattern, then perform cartridge cleaning to correct.
6. Using left/right arrow keys, navigate to 'print-mech button tap' menu.
7. Select Ok ('code = 0' will be displayed); click and hold Right Arrow until 'code = 43' is displayed. NOTE: enter 'code = 41' if 'code =43' does not activate the diagnostic print report.
8. Select Ok. Within one minute the Tap 43/41 diagnostic test pattern should be initiated and print. The test page prints.

--- 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 21/27/56 black cartridge should display 416 good nozzles (26x16 grid), while a good HP 22/28/57/58 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. [NOTE: HP 56/57/58 and HP21/22 cartridges are electrically similar]: http://inkjet411.com/?page_id=2358


B.2. Print Diagnostic Self-Test Page (only available on select HP 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.
