When I do a test page the other colours are fine but there is no cyan still. there any other steps I can take, all suggestions welcome.king at other bloggs it seems a common problem that cyan fails. Is this a printer fault?
Make sure the ink cartridges are properly vented and seated correctly
Press the Power button to turn on the printer, if it is not already on.
Place your fingers into the slot on the left side of the printer, and then gently lift up to open the cartridge access door. The carriage moves to the cartridge access area. Wait several seconds until the carriage is idle and silent before you continue.
Press the tab inward on the front of the old cartridge to release it, and then pull up on the cartridge to remove it from the slot.
Examine the vent area above the HP logo on the top of the cartridge.
If the cartridge still has the orange pull-tab attached, pull to remove it.
If the vent is clogged, use a straight pin to gently remove excess adhesive from the vent.
With a straight pin, gently remove excess adhesive from the vent
Turn the cartridge so that the cartridge contacts face downward, and then match the label color with the color dot on the carriage.
Slide the cartridge into its slot, and then gently press the cartridge down until it clicks into place.
Repeat these steps to inspect the vents on each of the cartridges.
Make sure that each cartridge is firmly installed in its slot. Run your finger along the top of the cartridges to feel for any that are protruding, and if any are, press down firmly until each cartridge snaps into place.
Close the cartridge access door.
