The following information is a list of the power requirements for
the Epson 9 and 24 pin printers and laser printers.
504 VA maximum

PSB No: P-0060

If the power requirements of a particular Epson printer is not listed please
refer to the appropriate User's Manual for the electrical specifications.
In the event that the User's Manual is not available, locate the silver label
on the back of the Epson printer.
This is a reliable source for the electrical
requirements.
The following formula is used to calculate the electrical
power requirements:
VOLTAMPS is equivalent to WATTS
VOLTAMPS = Volts * Amps
AMPS
BTU/HR = Voltamps/Volts
= Watts * 3.413
Example:
120V * 1A
= 120VA
120VA/120V = 1A
120VA is equivalent to 120W
120W * 3.413 = 409.56 BTU/HR
Heat output is rated in BTU/HR.

Tractor Pin Alignment
Date: 5/15/89
PSB No: P - 0044

Originator: RP
bd
The purpose of this bulletin is to insure the proper installation and alignment of
the FX- 850/1050 and LQ- 850/1050 push tractor assemblies.
There are two possible ways to install the tractor frame on the push tractor
assembly. If the frame is installed incorrectly, the tractor belt pins on the two
tractors will not be aligned, and the resulting printout appears to be slanted on
the page, or the perforated edge will be tom. This is caused by the marks on
the tractor shaft holders being 180 degrees ‘out of phase.’
When assembling a tractor, there are two grooves in the shaft, and two tabs
on the tractor shaft holder. lf the pins on both tractor belts are not aligned, it
will be necessary to disassemble the tractor, and rotate one tractor shaft holder
180 degrees, to bring it back into alignment with the other shaft holder.
Alignment can be verified by examining the marks in the shaft holders, which
will both be in the forward position when properly aligned, as shown in Figure
4- 51 below.

SUBJECT: FX-850/1050 UNDOCUMENTED BUFFER FEATURE
The FX-850/1050 dot matrix printers support an important feature
that is currently undocumented in the printer's User's manual.
The FX-850/1050 printers have the ability to enable or disable
the input buffer. This feature is controlled from the printer's
front panel by holding down the Load/Eject button during power
The printer will beep once indicating that the buffer is
disabled or will beep twice indicating that it is enabled.
The
condition of the input buffer may be changed back by simply
repeating the above operation. The printer's Self Test feature
may be used to determine the current setting of the input buffer
without changing it. Please refer to the Self Test examples shown
below.

Quick Reference for Printer Acoustic Noise Levels
Date: 6/5/91
PSB No: P-0016D
Page(s): 1 of 2 Originator: SLS
Sound intensity is measured in units called Bels (named after Alexander Graham Bell,)
or more commonly in tenths of this fundamental unit: decibels. In making noise
measurements a weighting network is applied in an attempt to match the frequency
response of the instrument to that of the human ear. The most common is the A
weighting network, with resulting measurements expressed in dB(A).
The following is a list of current product’s noise levels tested in accordance with
standards set by the International Standards Organization (ISO). The acoustic noise
levels for the 9 pin printers are averages while printing in Near Letter Quality (NLQ)
mode using continuous paper and are not guaranteed figures. The acoustic noise
levels for the 24 pin printers are averages while printing in Letter Quality (LQ) mode
using continuous paper and are not guaranteed figures. The acoustic noise levels for
the laser printers are averages while using single sheet paper and are not guaranteed
figures.
