Troubleshooting
Solving Ink System Problems
11-38
Checking Ink Systems
If you see the message “Check ink system / Ignore” you can either proceed
with the steps detailed in this section (press the
↑
key) or you can choose to
continue printing (press the
↓
key).
If you select “Check ink system” (
↑
), you will only be asked to check those
components for which the printer has detected an error.
If you select “Ignore” (
↓
), you can continue printing, but the quality of the images
produced by the printer may be impaired.
NOTE: If an ink system replacement was cancelled, or the printer lost power
during a replacement procedure, the machine may indicate that all four ink systems
need to be replaced. Removal and reseating the components of each ink system may
be all that is required. See 11-41, If You Have Problems Reseating a Printhead.
You should only replace the ink systems for which errors are shown on the front
panel. If more than one ink system shows an error, follow this procedure for each
failing system. Do not remove and reseat printheads too many times, as this can
lead to excessive wear on the electrical contacts, causing failures.
If problems persist, see 11-40, Persistent Ink-System Problems.
CAUTION If the problem occurred while changing ink system types (from Imaging to UV
Pigmented, or vice versa), be extra careful to verify that all ink cartridges match the
printheads in type. Installing the incorrect ink cartridge type can result in
contamination of both of the ink systems.
n Press the ↑
key for “Check ink system”, if that message is present on the front
panel.
Open the window when indicated.
Checking the Printheads
Check the printhead if there is a printhead error reported.
The message “Check printhead / Abort” is displayed. The flashing squares
indicate which printheads require checking. If you are unable to fix the
errors now, press
↓
to cancel (abort) the procedure.
n Remove the printhead completely from the printer carriage. You should ensure that
all four printheads are of the same type—Imaging (part numbers C1806A to
C1809A) or UV Pigmented (C1892A to C1895A).
