!IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY 1. Be sure that the power cord is unplugged before disassembling or assembling parts of the copier or peripherals. 2. The wall outlet should be near the copier and easily accessible. 3. Note that electrical voltage is supplied to some components of the copier and the paper tray unit even while the main power switch is off. 4. If you start a job before the copier completes the warm-up or initializing period, keep hands away from the mechanical and electrical components until job execution has started. The copier will start making copies as soon as warm-up or initialization is finished. 5. The inside and the metal parts of the fusing unit become extremely hot while the copier is operating. Be careful to avoid touching those components with your bare hands. HEALTH SAFETY CONDITIONS Toner and developer are nontoxic, but getting either of these into your eyes may cause temporary eye discomfort. Try to remove with eye drops or flush with water. If material remains in eye or if discomfort continues, get medical attention. OBSERVANCE OF ELECTRICAL SAFETY STANDARDS The copier and its peripherals must be installed and maintained by a customer service representative who has completed the training course on those relevant models. LITHIUM BATTERIES Incorrect replacement of lithium battery(s) on the FCU may pose risk of explosion. Replace only with the same type or with an equivalent type recommended by the manufacturer. Discard used batteries in accordance with the manufacturers instructions. SAFE AND ECOLOGICAL DISPOSAL 1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly if exposed to an open flame. 2. Dispose of used toner, developer, and organic photoconductors in accordance with local regulations. (These are nontoxic supplies.) 3. Dispose of replaced parts in accordance with local regulations.

LASER SAFETY

The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser chassis is not repairable in the field. Customer engineers are therefore directed to return all chassis and laser subsystems to the factory or service depot when replacement of the optical subsystem is required.

!WARNING

Use of controls not specified in this manual, or performance of adjustments or procedures not specified in this manual, may result in hazardous radiation exposure.

!WARNING FOR LASER UNIT

WARNING: Turn off the main switch before attempting any of the procedures in the Laser Unit section. Laser beams can cause serious damage to eyes. CAUTION MARKING:

SP5-827: Downloads the selected program from a flash memory card to the machine's flash ROM. Since the program size is only 2MB, it is possible to carry two different program versions on a single card, and selectively download either one of these. If you wish to carry two different programs on the same card, write one of these programs into card address space 000000h to 1FFFFFh, and write the other one into address space 200000h to 3FFFFFh.
Program Download (SP5-827) This SP is effective only if you boot the machine from the flash memory card as described below. If the download is unsuccessful, or if you decide that you do not wish to start the download, please turn the machine off and back on before resuming normal operation.
NOTE: Be sure to turn off the main switch before inserting or removing the flash memory card. Installing or removing a card while the main switch is on may damage the FCU. 1. Turn off the main switch. 2. Insert the flash memory card [A] into the card slot, with the card's "B" side facing the rear of the machine.

6.8.5 MODE ADJUSTMENTS
As a service person, you can use SPs 4-922 to 4-966 to further customize each of these original modes to meet specific user requirements. If the user is experiencing a problem with copy or fax quality, however, SP-based adjustment should be the last step. Always proceed as follows: 1. First, try changing the density notch setting. If that doesn't resolve the problem, then. 2. Try selecting a different original mode. If that also doesn't resolve the problem, then. 3. Try customizing the relevant original mode with SPs.

To customize.

First use SP4-921 to select the original mode that you wish to customize. Then enter the relevant customizations using SP4-922 to SP4-966. Refer to Section 5 for general information about the adjustments you can make. Note the following points: All SP settings are relative to the selected original mode. If you set the SP value to "0", the machine will use the default processing for that mode. If you enter an SP customization setting for an original mode that does not support that customization, the entry will have no meaning.
Default plotter customization settings for each mode. The following table shows the default plotter customization settings for each original mode. For information about adjustments, refer to the SP explanations in Section 5.
