1. Introduction
1. Introduction
Shimadzu Electronic Printer EP-90 is designed to be used with Shimadzu Electronic Balances. It is
easy to operate and useful for a wide range of applications and measurement administration.
Capability of battery operation is convenient for field use and transportation. Printing method is impact
dot on normal paper, which is suitable for long-term storage. Commands for printing, taring, auto print
and other balance functions can be sent to the balance with the EP-90 printer keys. ID number,
sample number, date and time can be input when printing the measurement results. Statistic
calculation function allows up to 1000 samples to be calculated and prints out the results.

(*2) Pressing the indicated key of EP-90 is equivalent to sending the command code here from a computer to the balance. For
further information on command codes, refer to the balance’s instruction manual. When the connected balance is not
equipped with the concerned function, the command is not recognized.
(*3) This key on EP-90 only turns it ON/OFF. With balance series for which detailed conditions of auto print function can be
selected (UW/UX, BW-K/BX-K etc.), the current settings on the balance remain valid. Refer to the balance’s instruction
manual for the details. Auto print is activated even with the series for which auto print cannot be set on the balance (BL,
EL/ELB etc.). As soon as stability is resumed after sample is loaded at zero display, the mass value is automatically printed out.
(*4) Only with the balances equipped with built-in clock. Refer to the balance’s instruction manual for details of built-in clock.
(*5) Receives the mass data from the balance, then EP-90 processes it and print out the checkweighing result. This function
works separately from the checkweighing functions of UW/UX series, BW-K/BX-K series, etc. Works with any balance
connected to EP-90.

Combined use of functions of EP-90 printer and functions of the balance
Date output, ID number, Sample number, xK Mode of EP-90 printer can be simultaneously used with
any function of the balance that involves data output. At every mass data output, these EP-90’s
functions operate the same way as when mass data is output by pressing the print key.
(e.g.) While formulation mode of the balance is used, if ID number and Sample number
functions are ON, lines of ID/Sample numbers are inserted before each component
mass value. Turn off EP-90’s functions if they are not desired for each component.
4.2 Basic Operation
While weighed result is displayed on the balance, if PRINT key of EP-90 or PRINT key of the balance
is pressed, the displayed value will be printed out with an indication of the weighing unit.
Depending on the balance series, additional data apart from weighed results such as calibration report,
application measurement results, date and time may also be output to EP-90 for printing. The PRINT
key of the balance or the balance's function menu should be used to output such items. Refer to the
balance's operation manual for instructions.

4. Functions and Operation
• Statistics of up to 1,000 samples can be calculated. When the number of samples reaches 1,000,
statistic calculation will be automatically performed, the results will be printed out, and the printer
will exit statistic calculation mode.
• Once the results of statistic calculation have been printed out and the statistic calculation mode
has been exited, the data that has been obtained up to that point can no longer be recalled.
The number of significant figures is 7 in EP-90. The calculated values may contain errors due to
the smaller number of digits of weighing data depending on the balance model.

4. Functions and Operation
4.8 Auto Print Mode
Auto print function prints out the weighed result automatically as a sample is placed on the balance
pan and the display stabilizes. Productivity is enhanced as the operator doesn't have to press any key.
(1) Press A.P. key
. The auto print function of the balance is activated and Auto Print lamp
of EP-90 will be illuminated.
(2) Press TARE key or O/T key of the balance or EP-90. The balance display will be zeroed.
(3) Place the sample on the balance pan. The weighed result will be automatically printed out
when the display stabilizes.
(4) Press A.P. key
while Auto Print lamp is illuminated to turn off the auto print function.
Notes
Conditions for data output in auto print mode vary depending on the balance series.
Refer to the balance instruction manual for UW/UX series, BW/BX series, BW-K/BX-K
series and AUW-D/AUW/AUX/AUY series. A.P. key of EP-90 only turns it ON/OFF. With
balance series for which detailed conditions of auto print function can be selected
(UW/UX, BW-K/BX-K etc.), the current settings on the balance remain valid. Refer to the
balance’s instruction manual for the details. Auto print is activated even with the balance
series for which auto print cannot be set on the balance (BL, EL/ELB etc.). Upon stability
is resumed after sample is loaded at zero display, the mass value is automatically
printed out.
4.9 Date Output
Press DATE key . Command is sent to the balance to receive date and time from the balance’s
built-in clock. Date and time are then printed out using one line each.
Every time DATE key
is pressed, DATE lamp will be turned on/off. While DATE lamp is
on, date and time are printed for each mass value that is printed.
Note
Date output function of EP-90 is not available with a balance that is not equipped with
built-in clock.

Communication and Other Settings
In EP-90 electronic printer, five settings including three communication settings can be selected with
the DIP switches. The default setting of the three communication settings are Shimadzu electronic
balance standard settings. Therefore, the communication settings do not have to be changed to
communicate with the balance. If any settings have been altered after the delivery, set them to meet
the balance's communication settings.
When using EP-90 simultaneously with the balance's WindowsDirect function.
• Set the baud rate at 300.
• Command keys of EP-90 are not valid.
• Date output function of EP-90 is not available.
5.1 DIP Switches
DIP Switches are mounted on the floor of the printer paper holder part. (See the figure) Remove the
printer paper. Turn the power OFF before operating DIP switches. The new settings will be made
effective when turning the power ON.
Caution
Turn the power OFF before operating DIP switches.

6. Maintenance
6.1 Refilling Printer Paper
The red lines marked on the printer paper indicate the paper is running short. Replace with a new roll
soon. For replacement, move printer paper shaft to the new roll from the old one. Refer to 3.3.3.
Loading printer paper.
6.2 Replacing Ink Ribbon Cartridge
Replace ink ribbon cartridge when print becomes faint. Open printer paper cover. Take out ink ribbon
cartridge by pressing the right end of it as shown in the figure.
Insert the new cartridge from straight above.
6.3 Replacing Batteries
The illumination of LOW BATT lamp indicates batteries need replacement. Replace with new batteries
soon. For replacement, refer to 3.3.2 Loading batteries.

7. Troubleshooting
7. Troubleshooting
Check the following points before calling for servicing.
Symptom Cause (→ remedy)
The power lamp does not light up when
the power switch is turned ON.
• AC adapter is not connected.
• AC adapter is not receiving power.
• The batteries are out.
No data can be received from the balance. • The connection cable is disconnected. (→ Switch off
EP-90 and the balance, then connect the cable properly.)
• The balance is not active for sending data, e.g., the
balance is displaying a menu.
• DIP switch settings have not been made effective. (→ Set
DIP switch while power is off, then turn the power on.)
• Sequence of switching power of EP-90 and the balance
was wrong. (→ See 3.4 Connecting the Balance)
The printed characters deviate.
No paper feed occurs.
• Paper jam is occurring. (→ Reload printer paper.)
No key entry can be made. • Printout is in progress.
• Data is being received from the balance.
No key switch on the balance works. • There is a data I/O error. (→ Switch off once, then switch
on again.)
The following data has been printed out. • The test program for servicing is running. If the power
switch is turned on with FEED key held down, the test
program is initiated.
