SOURCE: Printer doesn't work after putting in a new color cartridge.

This is a common problem with compatible cartridges where the chip on the cartridge is faulty, missing or is not making contact correctly with the printer cartridge connectors. The first thing to do is make sure that the plastic seal has been removed from the chip and that it is free of any residual adhesive etc. You can clean this with a cotton bud soaked in isopropyl alcohol or VCR tape head cleaner. DO NOT USE SURGICAL SPIRIT or any other cleanser as this will either leave a residue itself or damage the plastics and rubbers in the printer.

Once cleaned reinsert the cartridge and try again. If this is still unsuccessful the best solution is to return the cartridges to the vendor where you bought them and get another brand of cartridges or use genuine original cartridges. When you find a reliable manufacturer of cartridges, stay with them. Don’t forget to clean the print head and realign & recalibrate the printer at every cartridge change for optimum results. Also make sure that you use high quality paper for the best images results.

If you have colour or photo paper loaded in the Main tray when you align the printer, the alignment might fail. Load unused plain white letter or A4 paper into the Main tray, and then try the alignment again. If the alignment fails again, you might have a defective sensor or ink cartridge.
