Introduction Instructions Important information and the instructions in the documentation are designed as follows: Danger! Draws attention to an exceptionally great, imminent danger to your health or life due to hazardous voltages. Danger! Draws attention to a danger with high risk which, if not avoided, may result in death or serious injury. Warning! Draws attention to a danger with medium risk which, if not avoided, may result in death or serious injury.
Introduction General Safety This service manual is intended for qualified service and maintenance personnel. Further information to the operation of the device can be found the Operator's and Configuration Manuals. The following rules are for your general safety • Keep the area during and after maintenance operations clean. •...
Introduction Handling Electricity The following operations may only be performed by qualified electricians: • Any labor performed on electrical component groups. • Operations performed on the opened device while it is connected to the power grid. General precautions when commencing maintenance operations: •...
Changing Assembly Parts Dismounting the Cover Danger! Risk of death by electrocution. Before opening or dismounting the cover disconnect the device from the power grid and wait at least one minute until the device has discharged. Fig. 2 Dismounting the cover The printer cover can be dismounted completely including the front lid.
Changing Assembly Parts Changing the Print Mechanism Danger! Risk of death by electrocution. Before opening or dismounting the cover disconnect the device from the power grid and wait at least one minute until the device has discharged. Fig. 3 Changing the print mechanism 1.
Changing Assembly Parts Changing the Printhead Changing a printhead can be completed without fine adjustments to the printer. Changing the printhead is necessary when it is worn or a change of printing resolution is needed. 1 Connector data 2 Connector power 3 Threaded holes 4 Heating element Fig.

Changing Assembly Parts 12 13 Fig. 5 Changing the printhead Removing the printhead 1. Open the cover and fold the control panel (7) down. Push the energy regulator (5) and fold the printing module up with the printhead retainer (6). 2.
Changing Assembly Parts Changing the Print Roller Fig. 6 Changing the print roller 1. Open the cover and fold the control panel down. Push the unlocking mechanism and fold the printing module up. 2. Through the openings on both sides, push the pressure points (1) until the print roller assembly (2) snaps out of the locking mechanism.
Changing Assembly Parts Changing the Clutch and Brake of the Ribbon Rewinder The clutch (4) is a pre-constructed assembly group, the brake consists of the form disks (5, 7), the friction disk (6) and three springs (9). Fig. 7 Changing the clutch and brake of the ribbon rewinder Dismounting 1.
Changing Assembly Parts Changing the Brake of the Ribbon Unwinder 11 10 9 12 Fig. 8 Changing the brake of the ribbon unwinder 1. Fold up the printhead assembly group, undo the three screws (3) and remove the cover (2). 2.
Changing Assembly Parts Changing the Drive of the Cutter 12 10 Fig. 9 Changing the drive of the cutter 1. Fold down the control panel (1), release the cutter (4) from the brackets (3) and fold this up too. 2. Unhook the springs (3). 3.
Changing Assembly Parts 2.10 Changing the Blade of the Cutter Unit Fig. 10 Changing the blade of the cutter unit Danger! Danger of lacerations! Do not touch the blade without protective measures. 1. Fold down the control panel (1). 2.
Changing Assembly Parts 2.11 Changing the Circuit Board Danger! Danger of electrocution. Before opening the pinter cover disconnect the device from the power source and wait at least one minute until the device has discharged the remaining residual energy. 1 Circuit board CPU 2 4 Screws Connections...
Changing Assembly Parts 2.12 Changing the Power Supply Warning! Risk of death by electrocution! Before opening the cover plate remove the device from the power supply and wait at least one minute until the residual energy has dissipated. Fig. 12 Changing the power supply 1.
Adjustments Measuring the Winding Force The measurement of the un- and re-winding torque of the ribbon is determined by the tensile force on the test material that is connected to the ribbon retainer. The physical connection between the torque and tensile force is as follows. F= M / r force [N], torque [Ncm],...
Adjustments 3.1.2 Measuring the Breaking Force of the Unwinder Fig. 14 Measuring the breaking force of the unwinder Target Value Measurement Torque M Force F Break of the unwinder ribbon 3,9 - 4,5 Ncm 1,3 - 1,5 N 1. Insert the test device (3) onto a ribbon retainer (2). Note that the Spring tip must be placed in the grove of the ribbon retainer for a true result.
Adjustments Setting the Winding Force Fig. 15 Setting the winding force The settings of the winding force of the break (5) of the unwinder and the clutch (6) of the rewinder is done in the same way. 1. Insert the ribbon retainer (4) onto the winders. 2.
Adjustments Adjusting the Print Mechanism Changing the settings of the printing mechanic over and above a format change is only necessary when something other than the printhead is exchanged or if the printhead assembly group has been demounted or altered. The following identifiers point towards resetting the printing mechanic: - Printed image too light - Printed image blotchy or spotty...
14. If there is no camber adjustment necessary turn screw (3) clockwise until it clamps down minimally. 15. Turn down the heating energy in the configuration to 0 and test these results of the previous adjustments. With normal cab-standard material a clearcut, solid black printed image should have been achieved.
