Section 3: Internal Cleaning of Optical Drive Laser Lens
? This section will cover the diagnosis and cleaning of an optical drive laser lens.
DocSTAR systems have been equipped with an optical drive for the storage of documents
since their inception. These optical drives include:
? Panasonic 650MB 5¼” PD Disk Drive
? Fujitsu/Maxoptix 640MB 3½” MO Disk Drive
? Maxoptix 2.6GB T4/T5/T5-STAR 5¼” MO Disk Drive
? Maxoptix 5.2GB T6 5¼” MO Disk Drive
? Panasonic 4.7GB 5¼” DVD-RAM Disk Drive
These optical drives perform very well under normal circumstances. However, optical
drives require routine cleanings of the laser lens. This can usually be accomplished, on a
PM visit, by using the OEM cleaning kit provided for that particular optical drive. With age
and certain environmental conditions the optical drive may require a more in-depth
cleaning, which requires disassembly of the drive. The internal laser lens becomes
coated with a film, which distorts the laser’s focus and intensity. Even the cleaning kit
may be unable to remove this film. Once it has been determined that the (out of warranty)
optical drive is failing, even after using the cleaning kit, you should try to perform an
internal cleaning of the optical drive laser lens using the procedure you will learn in
Section 3: Optical Drive Cleaning Lab. You will need:
? A Grounding Strap
? A #1 & #2 Phillips Head Screwdriver
? A Precision Screwdriver Set
? Good-Quality Cotton Swabs
? Cleaning Alcohol
The following are possible indicators that an optical drive needs either a routine or in-
depth laser lens cleaning:
? The disk cannot be read from or written to by DocSTAR AND cannot be read from or
written to by Windows Explorer.
? During attempts to read from or write to an optical disk you receive ‘Device I/O’ error
messages in DocSTAR/Windows or a Blue screen.
? If the optical drive is inside a jukebox, the Jukebox may ‘Drop’ Disk Volumes randomly
due to a failure to read the disk. This will be indicated by Jukebox Admin reporting a
Volume as ‘(unknown).’
As with any repair, you must be cautious in performing the cleaning so as not to introduce
a new problem. Be very organized in disassembling the drive so that you will remember
how to reassemble it correctly. THERE ARE NO EXTRA SCREWS.
Note: It is possible that there is a true mechanical or electronic problem present, this
procedure does not ensure that you will be able to repair ALL optical drives.
