Chapter 1 Models and Options

The printer is – as standard – provided with one serial RS 232C port

and one parallel Centronics port. In addition, one extra interface

board can be fitted, see chapter 16.

Finally, you may want to inspect the electronics compartment. To

do so, carefully follow the instructions in chapter 13.

CAUTION!

Always turn off the power and remove the power cord

before opening the cover over the electronics compart-

ment! Dangerous voltage!

In the electronics compartment, check:

• Type of CPU board?

- Check number of Flash SIMMs.

- Check number and size of DRAM SIMMs.

• Any optional interface board fitted?

- Check type, straps and optional circuits.

Refer to chapters 15 – 16 for more information.

Chapter 1 Models and Options

If the printer is working and possible startup program can be

interrupted, the type of program in the printer can be identified.

Connect printer and computer, open a suitable communication

program, and start up the printer in the UBI Fingerprint's immediate

mode. The instruction FILES allows you to check what files the

various parts of the printer's memory contain. The statements

FONTS and IMAGES can be used for the same purpose regarding

fonts and images. Use the VERSION$ function to check version of

the UBI Fingerprint firmware.

You can read the setup in the Setup Mode or by means of UBI Shell,

which also allows you to print test label #5 containing the present

setup values. To enter UBI Shell if a custom-made autoexec-file

prevents access, lift the printhead and press any key on the printer's

keyboard (except the <Shift> key), then turn on the power while

continuing to press the key. When the UBI Shell countdown begins,

release the key and press <Enter> to start UBI Shell. Do not forget

to lower the printhead if you want to print e.g. test labels. Refer to

the Installation & Operation manual and to Appendix 1 in this

Service Manual for more information on the Setup Mode and the

UBI Shell startup program.

If the printer does not work, you may need to interview the user.

By now, you should have a fairly good idea what kind of printer you

will be working with. Compare with the list of standard features and

options on next page.

2. Front and Keyboard

The moulded front part is attached to the centre-line wall by means

of four #T20 screws and to the bottom plate by two #T20 screws.

The front moulding is provided with holes for mounting a cutter

connector (4-pin female DIN-type) and a slot, that in other printer

models using the same front, gives access to a memory card adapter.

Note that the memory card adapter in EasyCoder 601 XP is fitted

on the CPU board and is accessible through a slot in the rear plate!

At the top part of the front moulding, there is a cavity for the

keyboard/display assy. This assembly is affixed by means of two 2

mm hexagon grub screws underneath the keyboard part of the front

moulding.

The keyboard/display assy. is connected to P37 at the front of the

CPU board via a 10-p flat cable. This cable must be disconnected

before the keyboard/display can be removed.

The keyboard/display must be manipulated carefully when it is

lifted out of its cavity. Do not use any force! If the assembly seems

to be stuck, open the right-hand door and remove the left-hand cover

to check that the grub screws do not interfere with the brackets.

We also recommend you to remove the left-hand cover before you

start to fit the keyboard/display assy. back into the front moulding,

since it makes it easier to align the brackets with the grub screws.

lay, and a console pcb. The membrane switch keyboard is con-

nected to P2 on the console pcb. via a semi-transparent cable

running through a slot in the plate.

Keyboard Overlay

The keyboard overlay is self-adhesive with a non-permanent

adhesive, to allow easy replacement. Custom-made overlays could

also be printed and used to replace the standard overlays for

customized applications or in areas, where the English text is not

acceptable. Pulling away an overlay and replacing it with another

is a simple operation that the customer easily can perform himself.

Use isopropyl alcohol to remove any adhesive residue.

Keyboard

The keyboard is of membrane switch type and is glued to the

keyboard plate. There are 54 switches, but only 23 of these are used

in EasyCoder 601 XP. One switch is a Shift key, that provides a dual

functionality to each of the other keys. A resistor ladder gives

different voltages from each line and column on the keyboard so the

slave processor on the console pcb can decode signals from the

various switches (keys) by means of an A/D converter.

Keyboard Plate

The keyboard plate keeps the assembly together and to affix it in the

cavity of the front moulding. There are one slot for the display and

another for the cable running from the membrane-switch keyboard

to the console pcb. Two brackets at the lower edge are used to

connect the plate to the front moulding using two 2 mm hexagon

grub screws.

Console pcb

The console pcb manages the keyboard, the display, two of the three

LED control lamps, and the beeper by means of a slave processor.

The communication to and from the CPU board goes via an I2C bus

on a 10-p flat cable. This cable is permanently affixed to the console

pcb and connected to P37 a the front end of the CPU board.

The display is a LCD display with background light. It has 2 x 16

character with a 5 x 7 dots matrix. 8 characters are programmable.

There is no display contrast adjustment.

The beeper has a frequency between 104 and 9.999 Hz. It is used

to acknowledge when a key is pressed and to produce various

audible signals. The key-acknowledge signal can be controlled by

the UBI Fingerprint instruction KEY BEEP, whereas other signals

are controlled using the instructions BEEP and SOUND.

The left-hand LED control lamp (marked “Power”) shines green

when the power is on. Power on is also indicated by the display's

background light. The other two LEDs are programmable using the

UBI Fingerprint instructions LED ON and LED OFF. The centre

LED is green and the right-hand is red. The right-hand LED

(marked “Error”) is usually used to indicate that an error has

occurred.

PORTANT PRINTHEAD AND RIBBON INFORM

ATION

HEAD CLEANING

The use of any thermal transfer ribbons, other than those supplied by UBI, will invalidate

the printhead warranty.

UBI thermal transfer ribbons are engineered specifically for this printhead.

The quality of thermal and thermal transfer media supplies in this printer is also of great importance

for the quality of printing bar codes and a long life of the printhead. UBI has carefully matched the

paper we recommend/provide to the needs of this printer. We therefore strongly advise of using

only UBI recommended/provided supplies to ensure a high quality printing.

For optimum performance,

the thermal printhead requires

cleaning on a regular basis.

For cleaning information, see

the User's Manual.

3. Hatches and Doors

3.1 Right-Hand Door

The right-hand door gives access to:

• The paper supply

• The ribbon supply

• The print mechanism

The right-hand door is fitted to the bottom plate by means of two

hinges that allow the door to be swung down 180˚ to a vertical

position. The door is kept shut by means of a magnetic lock. The

door can easily be removed from the hinges by pushing it forward

until the snap-lock at the rear hinge becomes disengaged.

At the inside of the door, there is a label showing how to load the

paper and the transfer ribbon.

The hinges can be adjusted by means of the two pairs of #T10 Torx

screws visible on the outside. Possibly, the other parts of the hinges,

which are fitted to the bottom plate, may require adjustment too.

Shut the door, loosen the screws slightly and align the door with the

front moulding. Tighten the screws and check that the door runs

freely and is kept shut by the magnetic lock.

Chapter 3 Hatches and Doors

The front hatch gives access to:

• The front part of the print mechanism

• The paper cutter connector

• The optional label-taken sensor

The front hatch is fitted to the bottom plate by means of two hinges

of the same type as those of the right-hand door. The front hatch is

kept shut by a snap-lock and can be swung down almost to a vertical

position. The hatch can be removed from its hinges by pushing it to

the left until the snap-lock on the right-hand hinge disengages.

The front hatch can be replaced by an optional paper cutter unit, see

chapter 11.

Alignment is performed in the same way as the right-hand door, see

previous page.

The front hatch can be removed by pushing it to the left when open.
