2. Paper Empty Detection
The paper empty detector (CPED2, D1PED, D2PED) checks whether there is paper in the tray when the tray is lifted and stopped at a position
where it can feed paper, as well as during paper feed operation.
where it can feed paper, as well as during paper feed operation.
3. Paper Size Detection
The size of paper contained in each tray is detected based on the
status of each of desk rear edge detectors (switches) 1 to 4 as well
as on the destination-specific settings.

4. Paper level detection
The paper feeder detects the amount of paper remaining in the tray as one of four levels (100%, 67%, 33.3%, and zero), and displays the level
it has detected.
The paper feeder determines the remaining paper level based on how many times the paper level detector turns ON during the time between
the start of the lift-up of the paper feed tray and the activation (turning ON) of the upper limit detector.

The PWB’s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder.
LEAD-FREE SOLDER
The alphabet following the LF mark shows the kind of lead-free solder.
(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
When repairing a lead-free solder PWB, use lead-free solder thread.
Never use conventional lead solder thread, which may cause a breakdown or an accident.
Since the melting-point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the
exclusive-use soldering iron is recommended.
Never use conventional lead solder thread, which may cause a breakdown or an accident.
Since the melting-point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the
exclusive-use soldering iron is recommended.
(2) NOTE FOR SOLDERING WORK
Since the melting-point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering
capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land
separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when
completion of soldering is confirmed.
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron
tip after completion of soldering work.
If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.
