Prints test page ok but not anything else

Regarding your HP94 black ink cartridge error problem and inability to print to your HP PS 8450 printer, this type of problem is probably an internal micro-electronic failure inside the HP94 ink cartridge.

To determine which cartridge is causing the issue and/or to confirm an electrical problem with one of the ink cartridges (or possibly both), perform both the Internal Self-Test page along with the Pen Electrical tests (diagnostics) to evaluate the electrical condition of both ink cartridges....

Please first verify the age of the ink cartridge(s)....look at imprinted date on front (or back) of ink cartridge. If this 'warranty expiration date' has expired, then potential cartridge failures can occur due to internal corrosion, etc.

A. Ensure BOTH carriage/flex cables and BOTH ink cartridge contacts are thoroughly clean before proceeding: http://inkjet411.com/?page_id=1519

B. Print Self-Test Page:
1. Press CANCEL and SAVE simultaneously (SAVE is the left-most button before POWER on/off.)
2. Using left/right arrow keys, navigate to 'pen electrical test'.
3. Select Enter to print test - evaluate nozzle test pattern.

-- If the printer prints the self test page then this demonstrates the printer is generally functional and that the problem is likely with one of the ink cartridges. Please note this is a 'forced' service test...the printer will attempt to print the test page whether the cartridges are good or bad. If the Self-Test page can be successfully printed but regular/normal printing cannot, then one of the ink cartridges is likely internally damaged. Remove and replace suspect cartridge to confirm.

C. Perform Cartridge Diagnostics tests using either C.1 or C.2 procedure below (varies by printer model):

C.1. Tap 41/43 Diagnostics Test:
1. To enter the Manufacturing Tests menu, press the 3 small, round buttons on the front panel simultaneously for >5secs: 'OK', 'CANCEL', & 'SELECT PHOTOS' (or 'Print Photos')
2. Using left/right arrow keys, navigate to Special Reports (or System Menu). Select Enter.
3. Navigate to 'print-mech button tap' menu.
4. Select Ok ('code = 0' will be displayed); click and hold Right Arrow until 'code = 41' (or attempt 'code = 43' if nothing prints using '41') is displayed.
5. Select Ok. Within one minute the Tap 41 (or 43) diagnostic test pattern should be initiated and print. Refer to video to help evaluate test pattern. Refer to 2nd video for guidance on how to read the diagnostic test pattern: http://inkjet411.com/?page_id=1741


NOTE 1: A good HP 93/95/97/99 color cartridge should display 600 good nozzles, while a good HP 92/94/96/98 black ink cartridge should show 672 good nozzles. If the results yield anything different then the ink cartridge is likely damaged and will need to be replaced. For reference only, refer to the following HP Deskjet video which shows how to read the HP 93-97 ink cartridge diagnostic test print: http://inkjet411.com/?page_id=1741 (see 2nd video)

C.2. Pen Electrical / Error Bypass Procedure:
1. To enter the Manufacturing Tests menu, press the 3 small, round buttons on the front panel simultaneously for >5secs: 'OK', 'CANCEL', & 'SELECT PHOTOS' (or 'Print Photos')
2. Using left/right arrow keys, navigate to Reports Menu (or System Menu). Select 'pen electrical test'.
3. Select Level 1, 2, or 3. Enter to print test - evaluate nozzle electrical test print.


NOTE 2: Pen recovery level 1, 2 or 3 clears cartridge errors, unblocking the printer to permit you to print the TEST PAGE with the normal MENU / TOOLS /PRINT TEST PAGE choice to aid in printer evaluation.


NOTE 3: Cartridge Error Bypass Message (Emergency Printing only): The Pen Recovery Level 1 clears cartridge errors and permits you to print the TEST PAGE with the normal MENU / TOOLS / PRINT TEST PAGE choice.

It looks to me that your non Canon cartridge has blocked the print head. I see this all the time. Remember the compatables are not pigment based but just watered down ink so you can get it to flow through a syringe into the cartridge. This however is the classic outcome of trying to save a few pennies on an expensive bit of kit!

Light/faint prints usually are a result from clogged ink or air bubbles between the cartridge and print head (thus changing cartridge wont fix problem). Try printing the test page print from the machine (Ink Management -> set/ok twice). Answer the question(s) in the display and repeat this up to five times. The colors should be improved after 1-3 test prints usually.

Did you try to wipe the cartridge.Maybe there's a clogs. inside.

have you tried printing alignment page after you installed a new ink or cartridges if you did not try to print an alignment page first

hi!



Horizontal white lines usually indicate the ink cartridge is running out of ink or has some clogged ink nozzles. Try the following steps:

1. Some of the ink cartridge ink nozzles may be clogged with dry ink. Use the ink cartridge cleaning service to try to clear them. Follow the steps below:
   
   1. check if there is plain white paper in the Input tray.
      
   2. Press Setup .
      
   3. Press < or >to select Tools and then press OK .
      
   4. Press < or > to select Clean Print Cartridge and then press OK . The unit prints a test page.
      
   5. Examine the test page. If the print quality of the page is good, stop here. If the print quality appears to be getting better, run the Clean Print Cartridge utility again
      
2. If the self test appears better, Increase the copy quality setting (Normal or Best) and try copying again. If the quality is still poor, continue to the next step.
   
3. If the quality is still poor, one or more of the cartridges may be low on ink or empty. Follow the steps below to check the ink levels.
   
   1. Open HP Solution Center .
      
   2. Click Settings .

- hope it will help to resolve you problem...

I heard you can get the 3310 to do a pump up the tubes cycle but i don't know how to make it do it. Pressing the ok and cancel buttons when you power up didn't work for my machine. Which has too died a inkless black death!

Try to print a self test page from the printer itself, do these:

1. Press and hold the Cancel and the Color buttons at the same time.
2. Release both buttons.
3. The Self Test Report will be printed.

and check if it is the same output, if yes then follow the steps below:
