The machine sign on the printer's rear plate provides information

on type, part number, and serial number.

The voltage switch indicates the mains voltage for which the

printer is set up (115 or 230 VAC). Always check this switch before

connecting the printer!

You can also detect if the printer is ﬁ tted with any optional inter-

face board by means of the additional connectors on the rear

plate:

For further inspection of interfaces, the Electronics compartment

must be opened, as explained later in this chapter.

1.1 Identiﬁ cation, cont.

A Paper Cutter Unit is easily recognized by the extension on the

printer's front, where the cutter replaces the front hatch (see Chap-

ter 12). The EasyCoder 501 LinerLess has a spcial cutter.

By opening the front hatch (or the optional cutter unit ﬁ tted in its

place), you can check if the printer is ﬁ tted with a Memory Card

Adapter (see Chapter 13) and/or a Label Taken Sensor (see Chap-

ter 11).

1.1 Identiﬁ cation, cont.

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

do so, you will have to remove the left-hand cover plate.

For safety reasons, we recommend that you switch off the

printer and remove the power cord ﬁ rst.

(All high-voltage wires are insulated, but could be damaged and

should therefore be inspected at service.)

Using a #T10 Torx screwdriver, remove the four screws at the

bottom of the cover plate and the four screws along the upper edge,

hidden under the right-hand cover.

In the electronics compartment you may check, for example:

• Type of CPU-Board ﬁ tted?

• Fingerprint EPROM version?

• Conﬁ guration EPROM type?

• Optional ROM-expansion EPROMs ﬁ tted?

• Correct type of GAL circuits?

• Optional Real-Time Clock circuit (RTC) ﬁ tted?

• Type of interface on "uart1:"?

• Optional interface board ﬁ tted?

• Type of interface(s) on interface board?

Refer to the descriptions of the CPU-board and the various inter-

face boards in Chapters 17-23.

Chapter 1 Models and Options

1.1 Identiﬁ cation, cont.

The printhead density can be checked in two ways:

• Inspect the label stuck onto the outer side of the printhead,

which gives information on part number and date of

manufacture. Refer to the EasyCoder 501 Spare Parts

Catalog for part numbers.

• If the printer is working, you can print Test Label #1 in either

the Test Mode (see Chapter 25), in the Setup Mode (see

Appendix 1 or the Installation & Operation Manual).

If the printer is working and possible startup program can be

interrupted, the type of program in the printer can be identiﬁ ed.

Connect printer and computer, open a suitable communication

program, and start up the printer in the immediate mode of Inter-

mec Fingerprint. The instructions FILES "rom:", FILES "ram:"

and FILES "card1:" allows you to check what ﬁ les the various

parts of the printer's memory contains. 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 Inter-

mec Fingerprint ﬁ rmware.

The Intermec Fingerprint utility program PRSETUP.PRG allows

you to view the current setup values on the screen and also to pro-

duce a printout copy. You can also check the setup in the Setup

Mode or Test Mode, or by means of Intermec Shell.

If the printer does not work, you can get some clues from the

labels on the EPROM packages. You may also 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 fea-

tures and options on next page.

2. Front and Keyboard

2.1 Front

The moulded front part is attached to the center section using four

#T20 screws and to the bottom plate by two #T20 screws. The

front moulding is provided with holes for mounting a cutter con-

nector (4-pin female DIN-type) and a memory card adapter.

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

keyboard/display assy. This assembly is afﬁ xed by means of

two grub screws which can be loosened using a 2 mm hexagon

wrench.

2.2 Display/Keyboard

The keyboard/display assy. is connected to P-603 at the upper right

corner of the CPU-board via a 20-p ﬂ at 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 brack-

ets.

We also recommend you to open the right-hand door and remove

the left-hand cover before you start to ﬁ t the keyboard/display assy.

back into the front moulding, since it makes it easier to align the

brackets with the grub screws.

The keyboard/display assy. consists of a plate with two brackets, a

self-adhesive keyboard, an interchangeable slide, and a keyboard

interface pcb. with a 2 × 16 character LCD and three LEDs. The

keyboard is connected to P-3 on the interface pcb. via a semi-trans-

parent cable running through a slot in the plate. The cable to the

CPU board is permanently afﬁ xed to the interface pcb.

The contrast of the LCD display can be adjusted by means of the

potentiometer WR-1 on the CPU board. The potentiometer can

be accessed via a hole in the rear plate, next to the communica-

tion port "uart1:", see Chapter 4.2. The display should be adjusted

according to the prevailing light conditions when viewed from a

normal working position.

2.4 Slides

The slide can be removed through a slot at the right side of the

keyboard using a small pair of pliers. The slide can be replaced by

another one, for example to adapt the printer for a certain language

or a special application. There are three different standard slides

with English text as shown below
