Developed Image Test
Use the Developed Image Test to isolate print quality problems. You
might have to practice this procedure several times to get the timing
correct.
To run the Developed Image Test:
1. Set the paper exit lever to use the front exit.
2. Print the test page.
3. As soon as the leading edge of the paper is visible coming out
the front exit slot, turn off the printer.
4. Remove the print cartridge and look at the image on the
photoconductor.
Disk Test/Clean
This is a two hour test that should be performed only on a disk that
contains bad data and is therefore unusable.
This test destroys all data on the disk by doing a multi-pass write/
read on every block of the disk. Bad blocks are flagged and removed
from use. If over 2000 bad blocks are found the test stops and the
display indicates the disk must be replaced.
