Introduction
The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with refer-
ence to the timing of operation.
In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol , the arrow indicates the
direction of the electric signal.
The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results in
supplying the machine with power.
2. In the digital circuits, '1'is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low".(The voltage value, how-
ever, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'.
In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations of the microprocessors
used in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of the
DC controller PCB to the loads.
The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be com-
municated in the form of Service Information bulletins.
All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and be
able to identify and isolate faults in the machine."

1.1 Features
1.1.1 Feature
0018-3077
LBP3370 / LBP3310
1. Compact, high-speed and high-resolution printer
Regardless of its compact size that enables an installation on side of desks, this printer realizes the printing speed of 21 pages per minute in letter-size paper with
the resolution of 600 dpi.
2. Short wait time and low power consumption
The printer utilizes the on-demand fixing method that turns on the heater only during print operations. This shortens wait time, and enables low power
consumption during stand by period.
3. Automatic duplex printing
The printer enables an automatic duplex printing by installing the duplexing unit as a standard equipment in the printer.
