IQS 6 Copy/Print Defects

The machine should produce copies/prints free of defects. Any defects not explicitly covered
by this specification should be considered as a fault.
Show Through
No show through of the underside of the document handler should be visible when using Xerox
80gsm (20lb) or heavier paper as an input document. The check is made with the document
handler closed and in normal copy/print mode. Some show through may occur using 60gsm
(15lb) paper as documents.
Corrective action
If show though of the underside of the document handler is visible, ensure that the platen cush-
ion is clean. If necessary, install a new document cushion,

Paper Wrinkle
Paper wrinkles which result in the loss of information are unacceptable at any level. In any
mode, copies/prints containing wrinkles or creases of 84mm (3.3 inch) or less in length which
do not result in the loss of information may occur less frequently than 1 in 10 consecutive cop-
ies/prints in that mode. This is applicable to all base line papers; to simplex prints, provided the
paper is stored inside the printer and that the printer is operated within the environmental spec-
ification.
Corrective Action
Perform the checks that follow:
• That the paper stock conforms to the specification. Refer to
Specifications. Inform the customer if the paper is outside of the specifications.
• The customer's paper storage conditions. Paper must be stored in unopened packs in
cool dry conditions. Inform the customer if the storage conditions are not good.
• The environmental conditions. Refer to
the environmental conditions are outside of the specifications.
• For damaged rollers in the paper path.
– Wrinkles occurring before image transfer can be flattened by the fuser, resulting in a
wrinkled image even though the paper is flat.
– Wrinkles occurring after transfer tend to be creased into the paper and can be
caused in the fuser.
