Running Printer Diagnostics
Running Test Print
Use this diagnostic routine to print a specific type of test pattern. The test patterns are built into the printer
circuity, so Test Print is an excellent tool for isolating and diagnosing print quality problems. Through this
routine you can also specify the Test Print output destination - such as to the Face Up Tray, to a specific
Mailbox bin, or to the High Capacity Stacker.
To generate a Test Print
1. Enter Diagnostic Mode
The printer is in Diagnostic Mode and the LCD displays Chn-0
0 Fun-00.
2. Select a specific output destination from the table on the next two pages.
3. Use the Control Panel keys to enter the Chain number of the output destination.

10. Select a specific Test Print pattern from the table on the next two pages.
11. Use the Control Panel keys to enter the Chain number of the test.
12. Press Function Key [1] to switch the cursor from Chn and Fun.

To generate a Test Print without using Diagnostic Mode
OEM customers have the option of designing an QMS Video Controller that contains a Test Print switch or
button. The base QMS 3260/4032 printer, without an QMS Video Controller installed, can generate a Test
Print
only
through Diagnostic Mode.
