. Reload the roll. See Load a roll into the printer on page 32 .

. If some paper continues to cause an obstruction within the printer, it can often be cleared by loading
a rigid paper type into the printer.

. If you find that you have print-quality problems after a jam, try realigning the printheads. See Align
the printheads on page 71 .
Check the paper path
● This problem can occur when a roll has finished and the end of the roll is stuck to the cardboard
core. If this has happened, cut the end of the roll away from the core. Then feed the paper through
the printer, and load a new roll.
● Otherwise, follow the procedure described above, under Check the printhead path on page 163
Prints do not stack correctly in the bin
NOTE: This topic applies to the HP Designjet Z6100 42–in Printer only.
● Paper often tends to curl near the end of a roll, which can cause stacking problems. Load a new roll,
or remove prints manually as they are completed.
● If you are mixing prints or nesting sets of several different sizes, you might experience stacking
problems because of the different sizes of paper in the bin.
Automatic paper-cutter does not function
The automatic paper-cutter is disabled when the take-up reel is in use. To use the cutter on the paper,
uninstall (disable) the take-up reel on the front panel by selecting the icon, and then selecting Take-
up reel > Disable take-up reel.
NOTE: The automatic paper-cutter feature is disabled for some of the heaviest media types,
because they might damage the cutter.
Take-up reel paper jammed
If the paper is severely damaged on the take-up reel spindle core, do not use the printer's cutter to cut and
remove the paper. Instead, cut the paper manually as close as possible to the printer window, and then
remove the roll. See Unload a roll from the printer on page 36 .
Take-up reel does not wind
Predictably, if the take-up reel is not winding as anticipated, the printed output is likely to end up on the
floor. If the printer recognizes a problem with the take-up reel, it will interrupt the print job until the issue
is corrected. If the printer does not recognize a problem, the job will continue to print. The following table
highlights possible issues and solutions.
