GENERAL DESCRIPTION
[1] Caution
1. Laser caution
This laser facsimile is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH or IEC60825-1 standard. This means that
this machine dose not produce a hazardous laser radiation. The use of controls, adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.
this machine dose not produce a hazardous laser radiation. The use of controls, adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.
This laser radiation isn't a danger to the skin, but when an exact focusing of the laser beam is achieved on the eyes retina, there is danger of spot
damage to the retina.
damage to the retina.
The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing.
1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not an individual part.
2) Do not look into the machine with the main switch turned on after removing the toner/developer unit and drum cartridge.
3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and installing the optical sys-
tem.
4) The cover of Laser Printer Unit contains the safety interlock switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

3. Precautions for using Lead-Free Solder
1. Employing lead-free solder
This model employs lead-free solder.
This is indicated by the "LF" symbol printed on the PWB and in the service manual.
The suffix letter indicates the alloy type of the solder.
Example:
This is indicated by the "LF" symbol printed on the PWB and in the service manual.
The suffix letter indicates the alloy type of the solder.
Example:
Indicates lead-free solder of tin, silver and copper.
2. Using lead-free solder
When repairing a PWB with the "LF" symbol, only lead-free solder should be used. (Using normal tin/lead alloy solder may
result in cold soldered joints and damage to printed patterns.)
As the melting point of lead-free solder is approximately 40°C higher than tin/lead alloy solder, it is recommended that a
dedicated bit is used, and that the iron temperature is adjusted accordingly.
result in cold soldered joints and damage to printed patterns.)
As the melting point of lead-free solder is approximately 40°C higher than tin/lead alloy solder, it is recommended that a
dedicated bit is used, and that the iron temperature is adjusted accordingly.
3. Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is higher and has poorer melting point (flow), to prevent damage to the
land of the PWB, extreme care should be taken not to leave the bit in contact with the PWB for an extended period of time.
Remove the bit as soon as a good flow is achieved.
The high content of tin in lead free solder will cause premature corrosion of the bit.
To reduce wear on the bit, reduce the temperature or turn off the iron when it is not required.
Leaving different types of solder on the bit will cause contamination of the different alloys, which will alter their
characteristics, making good soldering more difficult.
It will be necessary to clean and replace bits more often when using lead-free solder. To reduce bit wear, care should be
taken to clean the bit thoroughly after each use.
