HP DesignJets 1050C and 1055CM Printers Service Manual
Performing a Service Test on a Failed Assembly
If possible, always perform a Service Test on the component/
assembly that you are about to replace, just to make sure that is the
component/assembly that has failed.
NOTE If the test on that component/assembly passes, you should NOT
replace it.
For information on the Service Tests and how to use them see
Chapter 4 - Service Tests and Utilities.
Performing the Necessary Service Calibrations
Is the printer calibrated correctly after replacing a component?
Refer to the table on Page 5-2 to determine when a calibration is
required.
NOTE Remember that certain Calibrations are required even if an
Assembly has been disassembled to gain access to another
Assembly or Component.
For information on the Service Calibrations and how to use them
see Chapter 5 - Service Calibrations.
Solving Image Quality Problems
Whenever an Image Quality problem appears, it is advisable to print
the Image Quality Print to help diagnose the problem. The Image
Quality Print will help you differentiate between possible printhead
errors and other problems such as incorrect front-panel selection,
driver or RIP configuration or mechanical problems. For
information on solving Image Quality problems see Chapter 6 -
Print Quality.
