Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to GP 14. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
CAUTION
Use care when moving the marking unit into the service position when hot. Ink can spill from
the ink reservoir located at the back of the unit if opened with too much force. Cross-colour ink
contamination could also occur.
CAUTION
Do not touch the exposed face of the printheads. Surface contamination or minor damage can
render the printhead inoperative.
• Check the media path for dust or debris accumulations. Clean as necessary, refer to GP
27 Cleaning Procedure.
• Inform the customer that using the best quality, smoothest media available will reduce the
likelihood of encountering spot deletions.
NOTE: Media containing cotton, linen or parchments can exhibit deletions due to surface tex-
ture. Carbonless media, especially in large quantities, can also exhibit deletions. Areas of
missing ink on envelopes that outline the seams and flaps is normal.
