Grid Test Print (Pgtype=06) - Canon CLC5000 Service Manual

3.3.6 Grid Test Print (PGTYPE=06)

Use the grid test print to check color displacement, right angles, and straight lines.
a. Color Displacement
If color displacement is noted, suspect a fault in the transfer belt.
Color displacement on this test print does not necessarily mean color displacement on
regular copies because of black text processing. The mechanisms are normal as long as color
displacement is not noted on regular copies. (Use this test to find out the location of dis-
placement and the color if color displacement is noted on regular copies.)
b. Right Angles/Straight Lines
If a fault is noted in relation to right angles or straight lines, suspect a displaced laser
beam or a fault in the beam detection mechanism.
Use Service mode 'TEST>PG>COLOR-C/M/Y/K' to make a mono or 3-
color selection.
