●
If the error follows the Printhead try to recover the Printhead by cleaning the contact again, if that
failed, replace the Printhead.
●
If the error does not follow the Printhead, clean again the Carriage Interconnect and check for
damage, check the Carriage Interconnect if appropriate.
3. If all the Printheads are rejected (the status message on the front panel does not show “OK” for all the
Printheads), perform the
1. Electrical System Menu on page 143.
The cutter does not function (Latex 360 only)
Under certain circumstances the cutter will not cut the substrate. This is mainly when the take-up reel is
enabled, but there are other circumstances when the cutter will not cut.
●
If the settings for the RIP have disabled the Cutter, but the customer has set the front panel settings to
cut, the customer could expect it to cut at the end of the job.
●
If the customer presses the ‘Scissors’ icon, but the Cutter is disabled on the front panel.
●
If the substrate being printed on cannot be physically cut because it is too thick.
The customer can enable and disable the cutter from the front panel (but remember this will be overridden
by the RIP). To enable the cutter from the front panel; select the settings icon, then substrate, then substrate
handling options > Enable/Disable.
Troubleshooting the printer heaters
Use this procedure if the resistors have failed. For this procedure you need a voltage-current tester like the
one shown in the pictures to measure resistances. If the printer has been printing, allow enough time (about
an hour) to cool down so that the resistance values will be correct when they are measured.
Important safety notice: Heating coils operate at hazardous voltages capable of causing death or serious
personal injury. Disconnect both power cords before servicing the printer.
Measuring Print Zone Heaters (Latex 360 only)
The resistive value of a print zone heater must be between 107.8 and 114.4 Ohms. If the value is not in this
range the heater must be changed.
The resistive value of the 3 printzone heaters can be measured from one of the cables connected to the Air
Curtain and Print Zone Heaters PCA (it is necessary to remove the E-Box extension cover to access the cable):
When the cable connector is in the position shown in the below picture:
●
The 2 pins on the left allow you to measure the value of the heater closest to the service station.
●
The 2 pins in the center allow you to measure the value of the heater in the center.
●
The 2 pins on the right allow you to measure the value of the heater closest to the ink delivery station.
