How to place an ink tank
Attention: Make sure that you replace an ink tank with a tank that contains ink 
of the same color.
1Hold the ink tank with the color of the label towards you.
The ink tanks are arranged in the same sequence as shown on the printer 
operator panel. From left to right, the sequence of the ink tanks is cyan, 
magenta, yellow, black (CMYK). A label on the ink tank indicates the color of 
the ink in the ink tank.
Note:Do not shake the ink tank or touch the opening of the ink tank.
2Slide the ink tank into the slot until you feel a resistance and stop.
Note:The ink tank fits in only one way. The ink tank fits only into the slot 
dedicated for the color. If you attempt to place the ink tank the wrong way or 
in the wrong slot, the ink tank will not fit. Do not attempt to force it.
3Press the dimpled recess in the ink tank inward and downward until the ink 
tank clicks into place.
When the printer detects the full ink tank, the ink level indicator on the printer 
operator panel displays 100%.

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 page186).
If the fallback mode is not enabled, the output quality will decrease. The print 
speed will not decrease.
