6-3 The Media Jams
The Media Jams
If an error message is displayed because the media
has jammed, immediately correct the problem. Fail-
ure to do so may damage the print heads.
 P. 114, [MOTOR ERROR TURN POWER OFF]
Is the media warped or wrinkled?
Many factors can cause warping or wrinkling. Refer to the
following and correct the problem.
 P. 111, Media Wrinkles or Shrinks, or Feed Is Unstable
Is the height of the print heads too low?
Try raising the heads higher. Media may inevitably warp or
wrinkle slightly, so adjust the height of the heads to take
this into account.

6-5 Media Wrinkles or Shrinks, or Feed Is Unstable
A variety of problems can occur if the media feed is not
smooth. This can cause such problems as poor printing
quality, contact with the media by the print heads, mis-
aligned positioning, media jams, or poor take-up. Take ac-
tion as follows.
Media Wrinkles or Shrinks
Is the media loaded and set up straight and securely?
Feed is not smooth when the media is not straight or is
tensioned unevenly on the left and right. Reload the media.
Was loaded media allowed to stand for some time?
Media may shrink or wrinkle if it is heated for an extended
time. When printing ends, switch off the sub power or re-
move the media.
Are the media clamps mounted?
When youre performing printing, be sure to attach the
media clamps.
Was the media loaded while the apron and platen
were at high temperatures?
Loading media while the apron and platen are heated may
cause shrinkage or wrinkling during printing due to sudden
warming. Before loading media, switch off the sub power
and allow the apron and platen to cool.
Is the temperature of the media heating system too
high?
Set the temperature to suitable values for the type of media.
 P. 34, Settings for the Media Heating System
Media Feed Is Not Straight
Is the media loaded and set up straight and securely?
Feed is not smooth when the media is not straight or is
tensioned unevenly on the left and right. Reload the media.
Are the media holders securely fastened in place?
If the retaining screws for the media holders are not tight-
ened securely, the roll may become unstable, impeding
smooth media feed. Firmly tighten the retaining screws so
that the media holders do not move.
Media Feed Is Not Smooth
Does the media strike some other object?
Make sure the media does not touch anything else. This
may affect printing, even when feed appears to be smooth.
Was loaded media allowed to stand for some time?
Media may stick to the platen if it is heated for an extended
time. When printing ends, switch off the sub power or re-
move the media.
Is the media too thick?
Media that is too thick may not only cause unstable feed,
but may scrape the print heads, resulting in malfunction.
Never use such media.
Are the grit rollers dirty?
Check to make sure the grit rollers are free of buildup of
foreign material such as media scraps.

6-6 The Print Heads Stopped Moving
If the print-head carriage stops over the platen, take ac-
tion immediately to prevent the heads from drying out.
What to Do First
Switch the sub power off, then back on again. (If the media
is jammed, then also remove the media.) If the print-head
carriage move to the standby position (the right side of the
main unit), it means the operation has ended successfully.
If the print-head carriage did not move, try switching off
the main power, then again switching on the main power,
followed by the sub power.
If the Heads Still Do Not Move
If the heads still do not move, carry out the following emer-
gency response measure, then contact your authorized
Roland DG Corp. dealer.
1. Switch off the main power.
2. Open the front cover.
3. Gently move the print-head carriage by hand as far
as the standby position.
4. Insert the cap-unit tool into the hole at the bottom of
the machine and turn gently. The cap unit rises.5. Make the guides at the edges of the print heads line
up  with the guides at the edges of the cap unit. Turn
the tool further to bring the cap unit near the heads.
6. When the heads make contact with the cap unit, turn
the tool one or two turns more.
Make sure the print heads are capped tightly.

6-8 If an Error Message Appears
This describes the error messages that may appear on
the machines display, and how to take action to remedy
the problem. If the action described here does not cor-
rect the problem, or if an error message not described
here appears, contact your authorized Roland DG Corp.
dealer.
[AVOIDING DRY-UP TURN OFF POWER]
The print heads were forced to standby position to
prevent them from drying out.
Operation cannot be continued. Switch the sub power off,
then back on. Opening the front cover while printing is in
progress causes an emergency stop. Never allow the print
heads to remain in this state.
[DATA ERROR CANCELING...]
Printing was stopped because a problem was found
in the data received.
Operation cannot be continued. Check whether the data
contains errors. Also, check for a problem with the connec-
tor cable or the computer, and redo the operation from the
step of loading the media.
[HEAD HEIGHT ERROR]
The height-adjustment lever for the print heads was
operated improperly.
Operation cannot be continued. Switch the sub power off,
then back on. To change the head height, use the [HEAD
HEIGHT] menu item.
 P. 81, Adjusting Head Height to Match Media Thickness
[HEATING TIMEOUT   CONTINUE?]
The media heating system did not reach the preset
temperature.
This occurs because the temperature of the location where
the machine is installed is too low. We recommend raising
the temperature. To quit printing, hold down
for one
second or longer. To continue waiting for the temperature
of the media heating system to rise, press
. To  start
printing immediately, press
.
[MOTOR ERROR TURN POWER OFF]
A motor error occurred.
Operation cannot be continued. Switch off the sub power.
Next, eliminate the cause of the error, then immediately
switch on the sub power. If the machine is allowed to stand
with the error uncorrected, the print heads may dry out and
become damaged.
This error may be caused by such factors as a mistake in
loading the media, a media jam, or an operation that pulls
the media with excessive force.
The media has jammed.
Carefully remove the jammed media. The print heads may
also be damaged. Perform head cleaning, then perform a
printing test and check the results.
The media was pulled with excessive force.
Excessive tension was applied to the media, and additional
action is necessary to recover from this state. First, move
the loading lever to the rear and adjust the media to create
a small amount of slack, then switch on the sub power.
[OPTION-DRYER IS NOT CONNECTED]
The optional auxiliary drying unit is not connected.
The [OPTION DRYER] menu item was set to ENABLE while
the optionally available auxiliary drying unit was not con-
nected. Turn off the sub power and main power switches,
then correctly connect the auxiliary drying unit.
[PINCHROLL ERROR  LOWER PINCHROLL]
was pressed without first lowering the pinch
rollers.
Press any key to clear the error. Pull back the loading lever,
then press
.
The pinch rollers were raised whilewas illu-
minated.
The error is cleared automatically after a short wait. Never
move the loading lever while printing is in progress.
[SERVICE CALL xxxx]
An unrecoverable error occurred, or part replace-
ment that must be performed by a service techni-
cian is required.
Note the number displayed, then switch off the sub power.
After you switch off the power, inform your authorized
Roland DG Corp. dealer of the number that appeared on
the display.
