I have a HP Professional Deskjet 1220C. It starts off printing full colour images ok but about a quarter of the way through it starts printing in red. Please help me.

Try the following below if it continues to print in red half way through then either your ink carts have expired or something is wrong with them if you are using coral draw to print images there is know problems with that I have listed the solution to that as well. please tell the results of the test page as well please. and also I have included a few other tests please run through these. The sample page can be used as a quick check of the image quality from the black and color print cartridges. Unlike most printing, this page prints from the bottom of the page to the top for user viewing during printing.

1. Turn the printer off and then turn it on again by pressing the POWER button.
2. Press and hold down the RESUME button and release it when the Power light starts to blink.

The sample page can also be printed from the Toolbox (provided the Toolbox is installed) to verify that the printer is connected to the computer properly and that the printer and printer software are working properly.

1. Double-click the Toolbox icon on the Desktop or run it from the HP Deskjet 1220C Printer program group.
2. Select the Printer Services tab and click Print a Test Page

--------------------------------------------------------------
Printing the diagnostic page The information displayed on the diagnostic page includes the printer model, serial number, service ID (born-on date), firmware revision, total page count and last error code (see Figure 2). If an error code (hex) number is displayed, it represents the last error that occurred regardless of whether the problem that caused the error has been fixed and the printer is presently operational. To print a diagnostic page see the following:

1. Turn the power on.
2. Press and hold down the POWER button.
3. While holding down the POWER button, press the RESUME button four times.
4. Release the POWER button.

Running the pen recovery diagnostic test If printouts have incomplete text or graphics that are not corrected by cleaning the print cartridges, use the pen recovery diagnostic test. The pen recovery diagnostic test is a three-level cleaning procedure that attempts to clear blocked print cartridge nozzles. The tests can be run either from the Toolbox under Printer Services or by pressing the button sequences below. The Level 1 print cartridge cleaning is a light cleaning mode. Use this level first to clear blocked nozzles.

1. Turn the power on.
2. Press and hold down the POWER button.
3. While holding down the POWER button, press the CANCEL button twice.
4. Release the POWER button.

After running the Level 1 print cartridge cleaning routine, run the nozzle pattern test explained in the "Printing the nozzle pattern test" section below to verify that the cartridge has recovered. If no irregular gaps are present on the printout of the nozzle pattern test, the print cartridge has recovered. If there are irregular gaps in the printout, run the Level 2 pen recovery. The Level 2 cleaning is an intermediate cleaning mode to be used if the Level 1 mode does not recover the nozzles.

1. Turn the power on.
2. Press and hold down the POWER button.
3. While holding down the POWER button, press the CANCEL button twice and the RESUME button once.
4. Release the POWER button.

After running the Level 2 print cartridge cleaning routine, run the nozzle pattern test explained in the "Printing the nozzle pattern test" section below to verify that the cartridge has recovered. If no irregular gaps are present on the printout of the nozzle pattern test, the print cartridge has recovered. If there are irregular gaps in the printout, run the Level 3 pen recovery. The Level 3 cleaning is the most intensive cleaning mode that takes about two minutes to complete. Use this level as a last resort in recovering clogged nozzles. This routine uses a considerable amount of ink.

1. Turn the power on.
2. Press and hold down the POWER button.
3. While holding down the POWER button, press the CANCEL button twice and the RESUME button twice.
4. Release the POWER button.

After running the Level 3 print cartridge cleaning routine, run the nozzle pattern test explained in the "Printing the nozzle pattern test" section below to verify that the cartridge has recovered. If no irregular gaps are present on the printout of the nozzle pattern test, the print cartridge has recovered. If irregular gaps still appear in the printout, replace the cartridge. NOTE: Do not use the pen recovery tests unnecessarily or the life of the print cartridge will be shortened. Printing the nozzle pattern test This test prints a pattern to determine which nozzles, if any, are clogged or not firing and can be used to verify a successful cleaning routine (see Figure 3). Look for irregular spaces or gaps in the test pattern; these indicate faulty nozzles.

1. Turn the power on.
2. Press and hold down the POWER button.
3. While holding down the POWER button, press the CANCEL button eight times and the RESUME button four times.
4. Release the POWER button.

Printing the calibration page This test provides calibration of the print cartridges. Calibration includes print cartridge alignment and optimizing the turn-on energy for the installed color print cartridge.

1. Turn the power on.
2. Press and hold down the POWER button.
3. While holding down the POWER button, press the RESUME button three times.
4. Release the POWER button.

Eight green checks, one on each line of the printout, signify that the calibration was successful. ----------------------------------------------------- Printing the infinite H test This test prints continuous pages of the letter H and is useful for troubleshooting paper feed problems or other intermittent problems that are difficult to replicate.

1. Turn the printer on.
2. Press and hold down the POWER button.
3. While holding down the POWER button, press the RESUME button eight times.
4. Release the POWER button
5. Press and release the POWER button to terminate the test.
