The copy paper weight
specification has been
narrowed due to the
changes in the paper
feed mechanism.
10 independent number
keys for faster and easier
operation. The access to
the SP mode has been
changed due to this
reason.
The pre-transfer lamp has
been removed. The same
PTL for E7 series is
available for the Robin
series as optional service
equipment.
Due to this, the transfer
corona adjustment
standard has been
changed.
Counter blade system Trailing system with
Setting powder should be
applied on the blade and
drum after servicing.
The main motor directly
drives the drum. The
drum motor and the drum
motor board have been
removed.

ROBIN
(A151 and A152)
For A151 copier, side
erase is performed by the
platen cover.
(A152 copier is the same
as E7 series.)
The development clutch
solenoid has been
removed.
Semicircular feed rollers
and corner separator
system.
Auto feed mechanism is
newly applied.
PE, J1 and J2. J1, J2 and J3. Sec. 2, page
Indication change only.
The basic detection
mechanism has not
changed.
Fusing lamp control
mechanism has changed
to achieve stable
temperature control of the
hot roller.
The grid voltage does not
change whether the
manual image density is
selected or auto image
density is selected (with
the exception of SP34
setting).
L correction method
The V
has changed to prevent
over applying the
exposure lamp voltage. A
white reference plate has
been added under the left
scale supporting bracket.
The drum temperature
correction has been
eliminated.
(A076 and A077)
FTR (Feed + torque
roller) feed system with
corner separators.
No auto feed. Sec. 2, page
The grid voltage is
different depending on
whether the image
density is manually
selected or the auto
image density mode is
used.
The V
applied at set intervals.

Conversion
An optics thermistor has
been added to monitor
the optics temperature for
the operation of the optics
cooling fan motor (A152
copier).
Since the cooling fan is
not installed on the A151
copier, the optics
thermistor monitors the
optics temperature to
prevent overheating in
the optics cavity.
However the copier may
stop for some extra
waiting time when the
thermistor detects a
certain high temperature
condition.
Since the elimination of
the PTL and the cost
reduction change to the
QL, the used toner
overflow detection cycle
has been changed.
1. When the copy
quantity reaches 80K
copies.
2. When the number of
the toner end condition
reaches 9.
to the copier at the
factory. A new pack is
necessary when installing
the machine.
The conversion for the
exposure lamp is
required. The conversion
for the dc power supply
board is not required.

E7
(A076 and A077)
The optics thermistor is
not equipped. The optics
cooling fan operates
during the copy cycle.

2. When the number of
the toner end condition
reaches 11.

Conversions for the
exposure lamp and dc
