NOTES:
• Some of tape recorders may not operate properly owing
to different specification or electrical characteristies
affected by signal distortion, electrical noise, leveldrop-
out caused after long years of use.
• When using the tape recorder fitted with the mixing
feature, it needs to disable the mixing function for both
recording and playback_
• Oepending on the
tape
recorder used, better reading
result may be attained when the red plug is unplugged
from the MIC[ack,
• As it may impede proper data transfer and verification
depending on the position of the volume control, tone
control, bass control, and treble control, try to find the
optlrnum
levelby varying their positions.
4. CIRCUIT DESCRIPTION
The CE-129P has two microprocessors; the P-CPU (inside
of CE-129P) by with data transfer is carried out with the
host CPU (M-CPU: inside of computer) and the prlnter
control PCU.
I
M-CPU to P-CPU data transfer method
Since there are no SEl1 and SEl2 used for the PC-1401
and El5500, OEVICE SElECT is dependent on the
contents of data.
(UEVICE SELECTJ
Since the data is transferred in bit by bit serial mode, above
steps (2) and (3) are repeated eight times to complete
transfer of one data, For instance, those steps are repeated
for 192 times (24 x 8) in order to transfer a 24 digits data.
The print commands, however, is sent out to the P-CPUat
the end of the data in a form of the code "00".

I
Cautions in exchanging the printer unit
In order 10 prevent print density variation causecl by
thermal head resistance variation, the printhead is classified
into three ranks of A, B, and C, and the rank is indicated
on the reverse side of the printer u~it F.P.C. After exchange
of the printer unit, relevant circuit change must be observed
in accordance with the procedure mentioned below.
I
Short JA when the rank A printer is used.
Leave all open when the rank B printer is used.
Shrt JC when the rank C printer is used.

After the above procedure, adjust by means of the 22-
Kohms protentiometer so that an optimum print quality is
obtalned. The circuit has been so designed as to attain the
best result with the potentiometer
Therefore, existence of aremarkable print density variation
might involve the following problems:

2_~ality change in the termal recording paper

2. Print density control method
• Before the print density adjustment, make sure that the
jumper pad is properly connected in a manner
cribed in Table-1.
• The VR should necessarily be set to the position
mentioned in Fig. 1. If set too much counterciockwise,
it may damage the printhead which mayaiso cause dot
omission.
