IQ 30 Blocking RAP
Use this RAP when the output has ink transfer between images in the output tray stack.
NOTE: A residual image may also occur when ink has been retained on the drum. Ink from an
earlier print then appears on the next sheet. Residual images may have a similar appearance
to blocking. Refer to IQ 23 Residual Ink From Previous Print RAP.
Ensure IQ 1 Image Quality Entry RAP is performed before starting this RAP.
Procedure
Advise the customer that this may be resolved by the use of lighter weight media. Alternatively
emptying the output tray more frequently may help. No other service actions will correct this
issue.
