Printhead

Cleaning the print head

1. Switch off the device.

2. Pull out the mains plug.

3. Remove material and ribbon.

4. Unscrew the two thumb screws on the print head mounting until the entire

printhead mounting can be rotated upwards on the contact shaft.

CAUTION! - The printhead is a sensitive electronic component and can be

damaged by electrostatic charges. Therefore, discharge any bodily static

electricity before coming into contact with the print head by touching the

base plate of the printer. The printhead does not need to be removed. Mark

the position of the printhead on the axle, if it is not flushed against the inner

or outer plastic ring.

5. Clean the print head using a dust-free cloth and cleaning fuel.

Fig. 1 Cleaning of the printhead – the

printhead needs not to be

unplugged (Fig: Dispenser

version).

CAUTION! - Do not use any objects with sharp edges. Metal objects may

never be allowed to come into contact with the print head surface!

6. After cleaning, return the print head mounting to its old position and

retighten the thumb screws.

Press the thumb screw on the tapered edge of the square axle and ensure

the exact positioning of the print head mounting on the axle. Also pay

attention to the position of the print head in relation to the edge of the label.

Basic factory settings: Flush against the inner black plastic plug.

7. Before switching on the device, check whether the print head cable is still

properly connected. If this is not the case, plug in the cable correctly.

Changing the print head

The print head is adjusted to the print head mounting during manufacture.

As a result the print head can only be replaced in conjunction with the print

head mounting.

1. Switch off the device.

2. Pull out the mains plug.

3. Remove material and ribbon.

4. Pull out both plugs in a horizontal direction from the print head.

Wait at least 3 minutes after switching off the device before removing the

print head cable from the print head. Mark the position of an axially

adjusted print head.

6. Unscrew the two thumb screws on the print head mounting until the entire

print head mounting can be removed from the contact shaft (Fig. 2).

Fig. 2 Take care not to touch the

connector contacts (1) or the

thermal edge (2) when removing

the printhead!

CAUTION! - The print head is a sensitive electronic component and can be

damaged by electrostatic charges. Therefore, discharge any bodily static

electricity before coming into contact with the print head by touching the

base plate of the printer. The print head may not be touched on the print

bar or on the plug-in contacts.

8. To install, move the new print head mounting to the old position and tighten

the thumb screws.

Before doing this make a note of the resistance value of the print head

(read off from the print head). When placing the print head on the print

head mounting, ensure that the print head is lying flat.

Press the thumb screw on the tapered edge of the square axle and ensure

the exact positioning of the print head mounting on the axle. Also pay

attention to the position of the print head in relation to the edge of the label.

Basic factory settings: Flush against the inner black plastic plug.

9. Plug the print head cable back into the print head.

10. The resistance value of the print head must be entered after putting the

printer into operation using the parameter SYSTEM PARAMETERS >

Head resistance.

64-xx – 64-xx Dispenser

Entering a false value can damage the print head!

Please also read the Service Manual, topic section "Service print module",

paragraph "Exchanging the printhead".

If the printout is worse than before, after a new printhead was installed, the

printhead position has possibly to be adjusted. This setting should be done

by a service technician.

For details refer to the Service Manual, topic section “Mechanics”, chapter

“Printhead adjustment” / “Adjusting the printhead position”.

Checking the print head

The printers of the 64-xx series are provided with a test function, which

tests the functio-nality of every single dot (dot check).

There are two different modes of operation with three different possibilities

to start a dot check:

Dot check modes Call by

Automatic dot check Automatic execution after powering on or in

printing pauses. To activate the automatic,

refer to parame-ter SYSTEM PARAMETERS >

Autom. dot check

Easy Plug: Add an optional D to the obligatory

#ER command (-> #ERD) to trigger a dot

check at the end of the print job.

Dot check on demand Dot check with subsequent status report that

informs about the number and the location of

the defective dots. Parameter

SERVICE FUNCTIONS > Head dot test

Dot check with subsequent printing of a pattern

which visualizes the test result. Parameter "

PRINT INFO/ Dottest endless/punched".

In Off-line mode by pressing the Apply+Feed

but-tons. Equals the call by parameter „Head

dot test“, but without the status report.

Defective dots are displayed by status

messages.

Tab. 2 The five ways to start a dot check.

Display message Die Displayanzeige für einen defekten Dot ist bei allen Dottestvarianten:

Status: 5103

Dot defective

If all dots are faultless, no display message appears.

Duration All five ways of dot checking test the entire printhead width. Therefore, the

test procedure may take from 10 s up to several minutes time (the wider the

printhead is and the more dots are defective, the longer).

03/13 Rev. 5.08-01 USER MANUAL Servicing and Maintenance

64-xx – 64-xx Dispenser

64-08 printers need up to 40 min time to perform a dot check. For this

reason, it is not recommended to use the "Automatic dot check" mode with

this type of printer.

CAUTION! - Never change the setting of a dot check parameter, during a

dot check is running!

Disregard may cause the printer firmware to crash.

Abortion If really considered necessary, please cancel the dot check by a reset

(press Feed+Cut+Online button)!

Never cancel a dot test by switching off the printer! This can destroy some

dots of the print head.

Rubber rollers

Cleaning the print roller

1. Switch off the device.

2. Pull out the mains plug.

3. Remove material and ribbon.

4. Only dispenser version: Remove the dispensing edge to gain easier access

to the print roller. To to so, unscrew both holding screws (1) ().

Fig. 3 When using a 64-xx dispenser or

Chess x dispenser, remove the

dispensing edge to gain easier

access to the print roller.

5. Unscrew the two thumb screws on the print head mounting until the entire

print head mounting can be rotated upwards on the contact shaft.

See paragraph "Cleaning the print head" on page 5.

The print head may or does not need to be removed. Mark the position of

the printhead on the axle, if it is not flushed against the inner or outer

plastic ring.

6. Now the print roller can be easily accessed from ahead. The rollers should

be turned gradually in order to clean them properly.

Fig. 4 Rotate the printhead upwards

befor cleaning it.

03/13 Rev. 5.08-01 USER MANUAL Servicing and Maintenance

64-xx – 64-xx Dispenser

CAUTION! - Only clean the print roller with a dust-free cloth and roller

cleaner. Never use knives or sharp-edged objects to clean the rollers!

Keeping impurities and dirt of any description away from the printing area

generally increases the running performance of the printer, and especially

that of the print head. The print image is also adversely affected by dirt and

other impurities.

7. After cleaning, return the print head mounting to its old position and

retighten the thumb screws.

Press the thumb screw on the tapered edge of the square axle and ensure

the exact positioning of the print head mounting on the axle. Also pay

attention to the position of the print head in relation to the edge of the label.

Basic factory settings: Flush against the inner black plastic plug.

8. Before switching on the device, check whether the print head cable is still

properly connected. If this is not the case, plug in the cable correctly.

Cleaning the feed roller

Every now and then, the feed roller and the contact pressure rollers should

be cleaned.

1. Switch off the device.

2. Pull out the mains plug.

3. Remove material and ribbon.

4. Remove the printhead.

For detailed information refer to chapter "Changing the print head" on

page 6.

5. Turn the feed roller stepwise while cleaning it using a cloth (Fig. 5) and

rubber cleaner until the entire roller is free of residue.

Shift the front material guiding (1) and the contact pressure rollers (2) for

better access to the roller.

Fig. 5 In order to clean the feed roller

remove the printhead and shift

material guiding (1) and contact

pressure rollers (2) aside.
