Replace a defective printhead
Introduction
The Océ TCS400 contains the following ten printheads:
■ Two printheads for cyan (C)
■ Two printheads for magenta (M)
■ Two printheads for yellow (Y)
■ Four printheads for black (K).
Always follow the instructions in the wizard on the printer operator panel when
replacing a defective printhead.
After you replace a defective printhead, the system performs an alignment. The
alignment requires the use of media. Make sure at least one roll of media is
loaded before you enter the 'Replace printhead' wizard.
Only replace printheads if they are defective. Changing printheads that are not
defective will shorten the printhead lifetime and cause problems with the ink
system.
Note: Only replace a defective printhead from the 'Replace printhead' wizard.
When to do
The system indicates which printheads are defective. Only replace the
printheads the system indicates.
The system uses the following methods to indicate defective printheads:
■ An error message prompts you to replace the defective printheads.
■ The printhead information card on the on-line screen indicates the
printheads with defective nozzles with an icon that shows a printhead with
the nozzles.
When the printhead nozzles are defective, you can continue to print. If the
fallback mode is enabled the output quality will not decrease. The print speed
will decrease.(see ‘Replace a defective printhead’ on page 186).
If the fallback mode is not enabled, the output quality will decrease. The print
speed will not decrease.
