My new canon pixma ip1500

by which I infer that Black only documents are ok, colored ones fail
the color ink cartridge is not seated properly, or is empty,
the OEM cartridges supplied with the unit are not full, dont last long, and dry up if unused
the connectors between the cartridge and the printer get dirty and may need to be cleaned
or there may still be the plastic security tab on the color cartridge.

not a guarantee, something to try
