During Maintenance

General

•Before you begin a maintenance procedure: 1) Switch the machine off, 2) Disconnect the power plug from the power source, 3) Allow the machine to cool for at least 10 minutes.

•Avoid touching the components inside the machine that are labeled as hot surfaces.

Safety Devices

•Never remove any safety device unless it requires replacement. Always replace safety devices immediately.

•Never do any procedure that defeats the function of any safety device. Modification or removal of a safety device (fuse, switch, etc.) could lead to a fire and personal injury. Always test the operation of the machine to ensure that it is operating normally and safely after removal and replacement of any safety device.

•For replacements use only the correct fuses or circuit breakers rated for use with the machine. Using replacement devices not designed for use with the machine could lead to a fire and personal injuries.

Organic Cleaners

•During preventive maintenance, never use any organic cleaners (alcohol, etc.) other than those described in the service manual.

•Make sure the room is well ventilated before using any organic cleaner. Use organic solvents in small amounts to avoid breathing the fumes and becoming nauseous.

8

•Switch the machine off, unplug it, and allow it to cool before doing preventive maintenance. To avoid fire or explosion, never use an organic cleaner near any part that generates heat.

•Wash your hands thoroughly after cleaning parts with an organic cleaner to prevent contamination of food, drinks, etc. which could cause illness.

•Clean the floor completely after accidental spillage to prevent slippery surfaces that could cause accidents leading to hand or leg injuries. Use dry rags to soak up spills.

Power Plug and Power Cord

•Before servicing the machine (especially when responding to a service call), always make sure that the power plug has been inserted completely into the power source. A partially inserted plug could lead to heat generation (due to a power surge caused by high resistance) and cause a fire or other problems.

•Always check the power plug and make sure that it is free of dust and lint. Clean it if necessary. A dirty plug can generate heat which could cause a fire.

•Inspect the length of the power cord for cuts or other damage. Replace the power cord if necessary. A frayed or otherwise damaged power cord can cause a short circuit which could lead to a fire or personal injury from electrical shock.

•Check the length of the power cord between the machine and power supply. Make sure the power cord is not coiled or wrapped around any object such as a table leg. Coiling the power cord can cause excessive heat to build up and could cause a fire.

•Make sure that the area around the power source is free of obstacles so the power cord can be removed quickly in case of an emergency.

•Make sure that the power cord is grounded (earthed) at the power source with the ground wire on the plug.

•Connect the power cord directly into the power source. Never use an extension cord.

•When you disconnect the power plug from the power source, always pull on the plug, not the cable.

After Installation, Servicing

Disposal of Used Items

1.If the machine has ozone filters, never operate the machine without the ozone filters installed. Always replace the ozone filters with the specified types at the proper intervals.

2.To avoid possible accumulation of ozone in the work area, locate the machine in a large well ventilated room that has an air turnover rate of more than 30m3/hr/person.

3.Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it may cause temporary eye discomfort. Try to remove with eye drops or flush with water as first aid. If unsuccessful, get medical attention.

Observance of Electrical Safety Standards

1.The machine and its peripherals must be installed and maintained by a customer service representative who has completed the training course on those models.

2.The NVRAM on the system control board has a lithium battery which can explode if replaced incorrectly. Replace the NVRAM only with an identical one. The manufacturer recommends replacing the entire NVRAM. Do not recharge or burn this battery. Used NVRAM must be handled in accordance with local regulations.

12

Safety and Ecological Notes for Disposal

1.Never incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an open flame.

2.Dispose of used toner, developer, and organic photoconductors in accordance with local regulations. (These are non-toxic supplies.)

3.Dispose of replaced parts in accordance with local regulations.

4.When keeping used lithium batteries in order to dispose of them later, do not put more than 100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat build-up.

•The danger of explosion exists if a battery of this type is incorrectly replaced.

•Replace only with the same or an equivalent type recommended by the manufacturer. Discard used batteries in accordance with the manufacturer's instructions.

Laser Safety

1.The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field.

2.The optical housing unit can only be repaired in a factory or at a location with the requisite equipment.

3.The laser subsystem is replaceable in the field by a qualified Customer Engineer.

4.The laser chassis is not repairable in the field.

5.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.

•Throughout the service manual this unit is called the "AIO" (All-In-One).

•The AIO is common to all machines of this series.

•There are no serviceable parts inside the AIO. (Disassembly of an AIO is never required.)

•When the AIO runs out of toner, the toner waste tank can be emptied and the toner supply tank can be refilled with fresh developer/toner.

•An AIO can be refilled up to three times (this is the approximate service life of the drum). The refillings greatly extend the service life of the AIO.

•The AIO can be easily removed and replaced by the user.

26

New Product Information

•The AIO has an ID chip which helps the machine to detect when an AIO is set and when a new AIO has been installed.

Feature Summary

General Features

Unlike other machines in their class, these machines are not inkjet or GelJet printers—they are laser printers. The three machines of this series have these common features:

•Thin printers have a small footprint and require little space.

•They are extremely light and easy to carry:

•4in1 models: 11.1 kg (24.5 lb.) or less

•3in1 models: 9.9 kg (21.8 lb.) or less

•Printer models: 7.2 kg (15.9 lb.) or less

•Their AIO units are identical and allow up to three refills with non-toxic developer/toner. Here is a quick feature comparison.

1. Product Information

The following features are not supported by these machines:

•Bulk paper feed unit (only one small tray is available)

•USB2 Print

•NRS support (no UZ, Basil, or Cumin options available)

•Memory expansion

•HDD expansion

•G3 expansion (no G3 option available)

•PictBridge

Duplex Printing

These machines have no mechanism for automatic duplexing.

•However, the operator can run a print job and print on the first side of the pages, remove the printed sheets from the output tray, turn the stack over so the blank side is facing up, load the stack in the paper feed tray, and then run another job to print on the second sides of the pages.

•Both portrait and landscape printing are possible. Duplex printing must be set up with the print application. For more details, refer to the operating instructions.

Important Points to Remember

These are very important points to keep in mind while using the service manual:

•Functionality. M135, M166, M148, M143, M167, M149, M168, M150, M151, M169, and M191 have both the ADF and flatbed unit.

•Smart Organizing Monitor. This utility (installed with the printer driver at installation) is used to configure the system and handle errors of all machines of this series.

•Message and error displays. M135, M141, M166, M148, M143, M167, M149, M168, M150, M151, M169, and M191 have a 2-line display that can show errors (SC codes) and messages. The M134, M165, M147, M142, M146, and M164 display are limited to two digits, and the M133, M162, M144, M163, and M145 have no display. The Service Mode of Smart Organizing Monitor can be used to view error messages for all machines.

•User Tool. The M135, M141, M143, M167, M149, M168, M150, M151, M169, and M191 have a [User Tool] button which opens the User Tool menu settings used to configure the machine. The Service Mode of the Smart Organizing Monitor is used to configure all machines.

•Scanning. The M135, M141, M165, M147, M142, M166, M148, M143, M167, M149, M168, M150, M151, and M169 both support applications that use the TWAIN and WIA drivers for scanning. The originals can be scanned and saved directly onto a computer disk.
