C3220 gradation error

[repeatcopiers]

Tech tried to do a full adjust gradation but it keeps telling him the test sheet isn't placed correctly. He is placing it correctly so what would cause this?

if this calibration page is from the Auto-Cal on printer--
u first need to tell him to read this PDF BELOW>>>

iR3200-3220 ITB Issues TP03.pdf

your ITB Patch calibration images are miss-aligned -
do to ITB belt slipping/ it needs cleaning and or replaced

the image on the page could be in the wrong spot or out of alignment. The reader position of the reader assembly could be in the wrong spot causing the issue as well.

Check your cassettes, white space margins and image alignment.

also print out your TEST PRINTS

PG 10 pattern/ make sure color blocks don't overlap
PG 6 pattern/ check the grid pattern

this is what the PG10 SHOULD LOOK LIKE

this below is a NG issue
pg10--.JPG
TEST CHART below shows poor alignment

THIS IS A GOOD PG6/ but the color grid lines never match up / overlay exactly as shown
