4. Clean the Cutter ramp with the damp cloth.

Clean the Encoder Strip
Cleaning the Encoder Strip is a vital part of the printer’s maintenance and can clear a variety of system
errors:
●
86:01 or 87:01 system errors and related mispositioning of the Carriage Assembly errors, such as
the carriage bumping into the side of the printer.
●
42:10 system error, related to failures starting and homing the carriage on the scan axis.
●
29:01 and 29:02 system errors which cannot be cleared even after installing new Maintenance
Cartridges.
●
There are occasions when an Encoder Strip that needs cleaning can cause paper loading issues,
as the Carriage cannot correctly detect the position of the paper.
With the type of pigmented ink that is used in the printer, the Encoder Strip cleaning must be performed
at regular intervals. Cleaning must be performed after every 10 liters of ink used. The front panel will
display a message when cleaning is required:
This message is displayed after every 5
th
job until the cleaning is performed, and the counter has been
reset. This procedure is normally performed by the customer. Instructions and materials are provided
within the User Maintenance kit. The kit can be ordered using part number Q6715A (HP Designjet
T7100 User Maintenance Kit).
