Phaser 7700 Color Laser Printer Service Manual
Analyzing the Test Print
Test prints provide several uses in troubleshooting printer problems.
■
Isolating problems to either the print engine or to the Image
Processing Board and host software.
■
Locating feed and paper transport problems.
■
Detecting print-quality and image registration problems.
Using Test Prints to Isolate a Problem to the Print Engine or to the Image
Processing Board
You can use test prints to determine if a problem is caused by a faulty print
engine or by a faulty Image Processing Board or host software.
Note
This procedure presumes you have investigated any
displayed error code or message. If not, please do so
now.
1.
Print a sample image from the host computer.
2.
Enter Printer Diagnostics and generate a test print.
3.
Compare both prints.
4.
If the problem occurs when you print from the host computer but does not
occur when you print from Diagnostics, the problem may be in the Image
Processing Board, in the print driver software, or in the application software
on the host computer.
5.
If the problem occurs when you print a test print, then the problem is in the
print engine.
Note
You can also use the above procedure to assist in
determining if a print-quality problem is caused by a
faulty print engine, Image Processing board or host
software. If the print-quality problem is an image
registration problem, refer to “Adjustments and
Calibration” on page 4-123 of this manual for instructions
on adjusting image registration.
Using Test Prints to Locate a Feed or Paper Transport Problem
You can use test prints to locate a problem with paper feed or with paper
transportation along the paper path.
Note
This procedure presumes you have investigated any
displayed error code or message pertaining to paper
feed or transport problems. If not, please do so now.
1.
Enter Printer Diagnostics and generate a test print.
2.
Follow the paper along the paper path to locate the cause of the problem.
