I replace my cartridges it says refer to printer documentation and will not print


These types of severe HP 74 black or HP 75 color ink cartridge errors (i.e. refer to documentation / incompatible cartridges, print cartridge(s) problem, etc.) typically indicate the internal micro electronics of the respective HP 74 black or HP 75 color cartridge are damaged. The cartridges electrical wire runs at rear and lower side of the ink cartridge, are very delicate and are somewhat susceptible to ink attack over time, which can lead to premature failures. In addition, the older the cartridge the higher the chance of an internal micro electronics failure. I suggest you first run a Tap 41 diagnostic test to check cartridges electrical health (this is a special forced service test, refer to video so you understand how to read the print out). You may also bypass the error (temporarily) on most models which use HP 74/75 cartridges.

NOTE: Unfortunately, alignment pages and internal self test prints will usually print Ok even if the cartridge is internally electrically damaged. Do not use these test pages as a proxy for determining whether a cartridge is good or bad, only the 'Tap 41/43' diagnostic test report can yield this information.


CONTACT CLEANING / SERVICE TEST DIAGNOSTICS:

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 and hold the CANCEL button.
2. Press the COLOR COPY button. Release both buttons.
3. The self test page should print. The printed pattern will verify printer is generally functional

--- The self test page is a 'forced' test print whether the ink cartridges are good or bad. Inspect color bars to verify proper nozzle/jetting health. If normal/regular printing is still not permitted then the problem is with either one, or both, of the ink cartridges. Activate Tap 41 test to confirm which cartridge is causing the issue.

C. Validate the cartridge's electrical health by running the 'Tap 41' diagnostics test. Refer to video procedure or .pdf document at the following links on how to activate and read the service test report: http://inkjet411.com/?page_id=536

1. Load Letter/A4-size paper into paper feed tray.
2. If any lights are blinking, first press Cancel to attempt to clear.
3. Press and HOLD the Cancel button, press Ok button once.
4. At 'Mfg Commands' menu, click Right Arrow once until 'uiaux service' menu is displayed.
5. At 'uiaux service' menu, click the Right Arrow until Special Reports menu is displayed.
6. Select Ok, then click Right Arrow until the 'print-mech button tap' menu is displayed.
7. Select Ok (Code = 0 will be displayed); click and hold Right Arrow until 'code = 41' is displayed. Use the Left Arrow if you need to decrease numerical count.
8. Select Ok. Within one minute the Tap 41 diagnostic test report should be initiated and print (whether ink cartridges are good or not, i.e. this is a forced print test). See following 4 paragraphs (or video) on how to interpret diagnostic report.....

NOTE: You may also refer to this document for specific printer model 'Tap 41' diagnostic & 'Cartridge Error Bypass' step-by-step instructions: http://inkjet411.retailinkjet.com/wp-content/uploads/2013/04/HP-74-75-Problem-Resolution_v10.pdf

--- Providing the color cartridge is partially functioning the Tap 41 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 75/75XL color cartridge should display 600 good nozzles, while a good HP 74/74XL 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. Refer to video on how to read the printout.

---- If the printer attempts to print the diagnostic test pattern (1 page) then the printer is generally considered operational and functional, if nothing is printed, but the printer attempts to print the pattern, then the tri-color ink cartridge is either empty, clogged or severely electrically damaged (black ink cartridge is not used). You can remove the tri-color cartridge, reactivate the tap 41 test and the printer will print the diagnostic test print in black ink.

You can also test general printer performance by running the 'Tap 10' diagnostic test, use same procedure above and enter "code = 10". Both the 'Tap 41' and 'Tap 10' tests are 'forced print tests' - the printer will make every attempt to print the pattern whether the ink cartridges are good or bad...the patterns should be utilized to diagnose cartridge health. If 'regular' printing is still not possible then one or both of the ink cartridges is damaged.


ERROR BYPASS OPTION (TEMPORARY ONLY):

NOTE: It is possible to 'temporarily' bypass the cartridge error message (for emergency printing purposes only), please refer to link above/below for video/documentation instructions: http://inkjet411.retailinkjet.com/wp-content/uploads/2013/04/HP-74-75-Problem-Resolution_v10.pdf

However, if the cartridge is determined to be electrically damaged, largely dependent on the 'Tap 41' diagnostic test results, the cartridge will eventually need to be replaced with a new one. With a marginally performing ink cartridge, this typically results in allowing 1 entire print job to be printed at a time. If this does not permit any print operations then the cartridge has severe internal electrical damage and will need to be replaced.

------------------------

*Many cartridges eventually do encounter problems or failures, especially after their original ink is gone and they are re-used, and this is often unrelated to the refill process. The "Incompatible Print Cartridge(s)" / "Print Cartridge(s) Problem" / "Refer to printer documentation" / "Cartridge Error: Cartridge must be replaced" / "Cartridge in left/right slot is not intended for use in this printer" / "Now printing alignment page" error messages are typically indicative of failed micro-electronics internal to the ink cartridge(s). Also note that it is common to have a marginally performing ink cartridge (which was performing ok before) in the adjacent slot (i.e. color), then when a marginally performing cartridge is installed into the other slot (i.e. black), both of the ink cartridge(s) then get flagged with electrical errors. Running the 'Tap 41' cartridge health diagnostics test will confirm the active electrical state of both cartridges.

CAUTION: Be advised, the use of compatible/clone cartridges (i.e. sold thru the internet from overseas) are known to be problematic and may cause printer errors. We do NOT suggest refilling these types of ink cartridges.....refilling of HP 74/75 original/genuine ink cartridges is only suggested!

Printer Photosmart 8450. Using HP black cartridge. Received message saying the printer did not recognize the cartridge because it was not HP. Removed it and tried several times to print. Gave up and...


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.

Printer has stopped printing blue


Make sure that you are inserting only genuine Lexmark cartridges in your printer. Removing then re-inserting the color cartridge into the printer is a quick to minor cartridge communication issues.
Make sure that your color cartridge still has substantial ink level for printing using the Lexmark Solution Center software on your computer.
Click Start > Programs > Lexmark X74-X75 > Lexmark X74-X75 Solution Center. Check the ink levels.
If color ink level is still good, then it probably just needs some cleaning. Print quality issues can be due to dirty or clogged print cartridge nozzles. From the Maintenance tab in the Lexmark X74-X75 Solution Center, click Clean print nozzles to fix horizontal streaks. Your printer will then print a test page. Try to print a color page again to verify that the problem with the blue color is fixed.
If the problem continues, try to insert a different known working color cartridge to identify if it's a faulty cartridge issue.

HP C3150 is printing green instead of yellow. How do i get yellow?


You should first check your ink levels to make sure you have enough of all colors. Do this through the printer toolbox on your pc. If the ink levels are fine you should print out a diagnostic page. Follow these steps to print out a test page: 1. Press and hold the cancel button 2.Press the start copy color button. 3. Release both buttons.
If there were problems with the test page run the clean print cartridges utility. This can be found in the printer toolbox in the device services tab.
If that fails as well, you should look at replacing your ink cartridges with new ones.

My hp deskjet 6940 inkjet printer doesn't show me level of ink in cartridge


Print a diagnostic page If the steps above have not helped, print and evaluate a diagnostic page to see if the cartridges or the printer is causing the problem.
  1. Make sure the printer is on and loaded with unused, plain, white paper.
  2. Press and hold the Power button and then press the Cancel button. Release both buttons. The diagnostic page prints. Figure 1: Power and Cancel buttonsc00584735.gif 1 - Cancel button 2 - Power button
Step 4: Note which cartridges printed which areas of the diagnostic page You must identify which cartridge printed which part of the diagnostic page, so that if you find defects on the page, you will know which cartridge is the problem. However, you can install different combinations of print cartridges in your printer, and different cartridge combinations print different diagnostic page patterns. Your diagnostic page may not look exactly like the picture below, but the right and left cartridges will print in the same areas of the page no matter which cartridges are installed. Figure 2: Diagnostic page layout (the patterns in each area may look slightly different on your page)c00584715.gif 1 - Printed by the right cartridge 2 - Printed by the left cartridge NOTE: If you are printing in reserve mode (one cartridge is missing), the missing cartridge's area of the diagnostic page will be blank. Step 5: Check ink levels NOTE: If you have installed a refilled or remanufactured ink cartridge, or a cartridge that has been used in another product, the ink level indicator is inaccurate or unavailable. Look in the middle of the diagnostic page. The bars with "E" (for "empty") and "F" (for "full") at each end show the ink levels in the cartridges. As ink is used, the solid color changes to a faded color.

Hi, I have an HP F4280 printer and the orange light of the color ink level is always lighting so i can't print anything (I am sure that my color cartridge is not already empty). What can I do? Oh yeah,...


There is only enough ink in the HP 60 cartridge to print approximately 200 pages. Also, the ink stored in the cartridge can dry quickly even it it's not used so you may be out of ink or the ink in the cartridge has dried up. Refill your cartridge with a kit or replace it with a new one. The ink level indicator is only an estimate any way. See pg 72 of the user manual which you can obtain here: http://h10032.www1.hp.com/ctg/Manual/c01374711.pdf

Color ink cartridge is defective but black cartridge is okay.


No, you can't print with only one cartridge in the printer. The printer needs both of them to close the electric circuit. Remove the color cartridge and inspect it. Clean the electric contacts on it- sometimes, when the contacts are dirty, the printer cannot recognize the cartridge. If that doesn't do the trick, you will need to replace the color cartridge.
