TIP: You can disable the take-up reel from the front panel by selecting the icon, then Take-up reel > Disable take-up reel. ● During double-sided printing. Take-up reel substrate jam If the substrate is severely damaged on the take-up reel spindle, do not use the printer's cutter to cut and remove the substrate. Instead, cut the substrate manually as close as possible to the printer window, then remove the roll. If the problem remains after removing the substrate jam, unload the take-up reel from the front panel and load it again. 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 interrupts the print job until the issue is corrected. If the printer does not recognize a problem, the job continues to print.

(where

IPaddress

is the IP address of your printer) to help you to

determine the correct value to apply.

The automatic cutter does not work

The automatic cutter is turned off in any of the following cases.

●

When it has been manually disabled from the front panel: Select the

icon, then

Substrate handling

options

Disable cutter

●

When printing on some particularly heavy substrate types, which it cannot cut.

●

When the take-up reel is enabled.

TIP:

You can disable the take-up reel from the front panel by selecting the

icon, then

Take-up reel

Disable take-up reel

●

During double-sided printing.

Take-up reel substrate jam

If the substrate is severely damaged on the take-up reel spindle, do not use the printer's cutter to cut and

remove the substrate. Instead, cut the substrate manually as close as possible to the printer window, then

remove the roll.

If the problem remains after removing the substrate jam, unload the take-up reel from the front panel and

load it again.

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 interrupts the print job until the issue is

corrected. If the printer does not recognize a problem, the job continues to print. The following table

highlights possible issues and solutions.

Issue

Print job interrupted?

Possible cause

Possible solution

Blinking quickly

Take-up reel is not

winding

Yes

The sensor beam was

blocked for more than 3

seconds.

Make sure that the take-

up reel sensors are not

blocked by a strip of

substrate or any objects.

See the following

graphic. Make sure that

the collection bin is

placed behind the foot

brace.

Also ensure that the

take-up reel power

switch is in the On

position.

Blinking slowly

Take-up reel is not

winding

The sensor cables are

loose or unplugged.

Ensure that the sensor

cables are correctly

secured.
