System Error: 44:YZ (T1100/T1100ps/T610 ONLY)
Problem
Description:
The 44:10 system error signifies an electrical error with the Aerosol Fan, or a
connection error.
Please note that only T1100/T1100ps/T610 printers manufactured before
mid-February, 2008, have aerosol fans.
Corrective Action: Try the following:
1 Did you replace the Formatter before the error occurred? Is the printer a
T1100/T1100ps/T610? If so, see If the error occurred after replacing the
Formatter below.
2 Switch the Power OFF from the back of the Printer and disconnect the Power
cord. Reconnect the power cord and power On the Printer.
3 Check that the Aerosol Fan cable is not damaged and is correctly connected
to the PrintMech PCA
4 Replace the Aerosol Fan Assembly. See Aerosol Fan Assembly (T1100,
T1100ps, T610 ONLY) on page 6-71.
If the error occurred after replacing the formatter
As a design enhancement from mid February, 2008, the HP Designjet T
Series printers do not include an Aerosol Fan.
A small quantity of printers manufactured after mid February, 2008, are
displaying the system error 44:10 if the formatter has been replaced,
because the formatter contains a previous firmware version (previous to
version 6) that checks for a fan connection.
Corrective Action
Check the serial number plate which is located at the rear of the printer. If
the printer was built after mid February, 2008, replace the Formatter using
the following part numbers:
HP Designjet T1100 Printer: Q6683-60021 (or any formatter service kit
including fw 6 or superior)
