INTRODUCTION
The UBI EasyCoder 501 is a series of modular
multipurpose thermal transfer/direct thermal printers.
They come in three main models intended for different
types of applications:
• EasyCoder 501 is mainly intended to be controlled
by a host computer using standard or custom-made
application software, e.g. the UBI LabelShop labeldesign program for Microsoft Windows. Being a
low-cost alternative, it has a somewhat lower print
speed and fewer options than the other members of
this printer family. EasyCoder 501 can be fitted with
an optional scalable fonts kit that allows the use of
outline fonts in Speedo and TrueType format. Externally, the EasyCoder 501 is distinguished by the
single Print key on its front panel.
• EasyCoder 501 E (Enhanced) offers higher print
speed and a larger keyboard than EasyCoder 501.
The large number options in regard of media handling and computer connection makes this printer a
highly flexible alternative. It is recommended for
installations, where you want to switch between
different application programs, or create your own
programs in the built-in UBI Fingerprint programming language. EasyCoder 501 E can, as an option,
be fitted with a scalable fonts kit that allows the use
of outline fonts in Speedo and TrueType format. This
printer model can easily be recognized by its 22-key
membrane keyboard.
• EasyCoder 501 SA is just as quick and flexible as the
EasyCoder 501 E model, but is fitted with a special
“Stand-Alone” software, which allows the printer to
be operated independently, without any computer
connection. This printer model is fitted with a large
built-in alphanumeric keyboard. The EasyCoder
501 SA can easily be “docked” to a personal computer and loaded with label texts and formats created in
the UBI LabelShop label-editing program running
under Microsoft Windows.
Information on the different models and options can be
found in the Technical Manual, which also describes
installation and computer connection.

IMPORTANT PRINTHEAD AND RIBBON INFORMATION
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.

The paper stock compartment becomes accessible when the
right-hand and front doors are swung open. Although the printer
is operable when the doors are left opened or completely
removed, you are strongly recommended to keep them closed
during normal operation, so as to prevent the printer mechanism
from being exposed to dust.
The adapter for 76 mm (3") paper roll cores is included in the
delivery and can be fitted on the paper supply spool.
Lock the adapter by means of the screw, making sure that the
screw hits the evenly rounded plastic surface, rather than the leaf
spring or the cam.

The printer can be supplied with paper from e.g. an
external label roll or a box of fan-fold tickets via the
upper or lower slot in the rear plate.
The lower intake slot is preferred when the supply is
placed lower than the printer.
As an option, the printer can be fitted with a set of
fan-fold guides in either intake slot.
The fan-fold guide can be supplemented with an
additional guide shaft which replaces the label slack
absorber. Thread the paper between the guide shafts as
illustrated from either the upper or lower intake slot.
When an external paper supply is used, take precautions
to protect the paper stock from sand, grit and other hard
particles, that may damage the printhead!

PRINTHEAD CLEANING
Open the front and right-hand doors.

2
Remove the transfer ribbon and paper supplies.
Cleaning of the printhead on a regular basis, preferably in
connection with each ribbon or paper reload, is important for the
life of the printhead and for the printout quality. Below is a
description on how to clean the printhead by means of Cleaning
Cards. If additional cleaning is required, e.g. for removing
adhesive residue from the print roller or dispenser edge, use a
cotton swab moistened with isopropyl alcohol.
Caution:
Isopropyl alcohol [(CH
3)2
CHOH; CAS 67-63-0] is a highly
flammable, moderately toxic and mildly irritating substance.
Cleaning Card
This pre-saturated disposable Thermal Printer Cleaning Card is
designed to safely and effectively remove all dirt, ink, tape,
residue, adhesive and other contaminants from Thermal Print Heads.
This Cleaning card will improve print quality and the life of the
Thermal Print Head.
NOTE: For Thermal Transfer Printers, remove ribbon.
• Open pouch and remove EasyCoder Cleaning Card.
• Lift thermal printhead and insert EasyCoder Cleaning Card.
Lower printhead and press FEED or PRINT. If printer returns
an error message, repeat the procedure but press FEED
or PRINT before lowering the printhead. The printer will start
feeding after printhead is lowered.
• Allow a few seconds for EasyCoder Cleaning Card to dry,
then insert dry card for a second time, feed to remove remaining
contamination.
• Remove Cleaning Card and dispose of properly.
• Use EasyCoder Cleaning Cards before inserting every roll of label
stock or ticket stock.

PRINTHEAD REPLACEMENT
The quick-mount thermal printhead is easy to replace:
• Turn off the printer.
• Open the front and right-hand doors.
• Lift the printhead and remove the paper and ribbon stocks.
• Turn the printhead lock handle counter-clockwise to open position, see illustration.
• Remove the printhead assy carefully as far as the cables allow.
• Remove the two printhead cables by pulling at the connectors.
• If you want to change the lateral position of the printhead, move
the #T20 Torx screw to its alternative position (8 dots/mm
printheads only).
• Connect the two cables to the printhead.
• Fit the replacement printhead assy back into the bracket so the
guide screw fits into its slot and the rear end of the assy is held by
the two lugs. You can switch between 8 dots/mm (203.2 dpi) and
11.81 dots/mm (300 dpi) printheads at will.
• Turn the locking handle clockwise to locked position.
• Load paper and transfer ribbon. Then lower the printhead.
• Turn on the power. At power-up, the printer will automatically
reset itself to the characteristics of the printhead in regard of head
resistance and density.
• Close the front and right-hand door and the printer is ready for
operation.
