The printer hangs during printing and displays ‘processing’
It has been seen under certain circumstances that the printer hangs whilst printing, this may happen
immediately after printing, or only a partial print. In some cases when this occurs if the machine is restarted a
system error 79:04 is displayed, although restarting again appears to clear this error. After this point,
although the printer displays that it is in the “Ready” state, attempting to print anymore plots will once again
hang the printer, including internal demo plots.
79:04
Cause Solution
The reason for this error is that a large spooled file (11 GB for
example) has been sent to the printer and has been placed in the
disk partition which is related to the print queue. The file
completely fills up all the disk space, because of this it will never
successfully print, and so the file remains in the disk partition.
Even after restarting the printer the file remains, subsequent
print requests also fail as there is not sufficient space available in
the partition to process anything else.
Perform the following few steps to clear the error.
1. Check that the firmware is the latest available
2. Turn Off and ON the printer.
3. Set Queue to OFF.
4. Set ‘When Start Printing’ to ‘Immediately’.
Please guide the customer through the front panel of the printer
to set up the “Queue” to “OFF” and “When Start Printing” to
“Immediately”.
Wipe disk solution
If the above procedure does not clear the error, use the wipe the
hard disk procedure (Unsecure mode)
See Disk Wipe DoD
5330.22’M on page 106. This will delete all previous jobs, ICC
profiles and paper presets that were present on the hard disk.
This procedure has an advantage for the customer in that it
solves the issue without the need to wait for an onsite engineer
to come to their premises and remove and replace the HDD
(which would also have the same affect of deleting all the
previous jobs, ICC profiles and paper presets). The whole
procedure should not take more than 30-35 minutes.
Important step is that you need to select the Unsecure mode.
The printer continuously rejects printheads
To resolve printhead rejection problems, do the following.
1. Clean the flex contacts on the Printhead and in the Carriage Assembly using the Carriage Interconnect
Wiper (see
Carriage Interconnect Wiper on page 79) and try again.
2. If all the Printheads are rejected (for each Printhead, the status message on the Front Panel does not
show 'OK') then perform the Carriage Assembly Test
Carriage Assembly test on page 87..
A new maintenance cartridge is incorrectly detected as ‘used’
This can occur if the printer has detected the previous Maintenance Cartridge was nearly full, and when a new
Maintenance Cartridge is installed the Front Panel displays an error that the cartridge is ‘used’. To resolve the
problem, manually reset the counter of the Maintenance Cartridge
Reset Life Counters on page 103.
Cover sensors are not working
To resolve cover sensor problems, do the following.
