Precautions

1.3 ESD Precautions

Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly called “Electrostatically Sensitive (ES) Devices” or ESDs. Examples of typical ESDs are: integrated circuits, some field effect transistors, and semiconductor “chip” components.

The techniques outlined below should be followed to help reduce the incidence of component damage caused by static electricity.

Caution >>Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

1.Immediately before handling a semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, employ a

commercially available wrist strap device, which should be removed for your personal safety reasons prior to applying power to the unit under test.

2.After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface, such as aluminum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity of the assembly.

3.Use only a grounded tip soldering iron to solder or desolder ESDs.

4.Use only an “anti-static” solder removal device. Some solder removal devices not classified as “anti-static” can generate electrical charges sufficient to damage ESDs.

5.Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to damage ESDs.

6.Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most replacement ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a comparable conductive material.

7.Immediately before removing the protective shorting material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed.

8.Maintain continuous electrical contact between the ESD and the assembly into which it will be installed, until completely plugged or soldered into the circuit.

9.Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as the brushing together of clothing fabric and lifting one’s foot from a carpeted floor, can generate static electricity sufficient to damage an ESD.

3)2nd Transfer High Voltage : T2(+)

•Function: voltage used to transfer the toner primarily transferred on ITB again onto paper.

•Output voltage: Max +5.0KV 3%(Duty variable, no load)

•ERROR type: if T2(+) output fails, the toner on ITB will not be transferred to paper normally and the image will be blurred.

4)T2 Cleaning Voltage : Clean : T2(-)

•Function: prevent reverse side of paper from being dirtied, by recovering the negatively charged toner remaining at Transfer Roller and sending it onto ITB.

•Output voltage: with no feedback control, output fixed voltage(-1300V 15%)

•ERROR type: reverse side of paper will be dirtied.

5)Supplying Voltage : Supply AC+DC(-)

•Function: voltage that makes toner to develop on the area exposed by LSU by means of potential difference, output will be the voltage of AC+DC overlapped form.

•Output voltage: AC 600V ~ 2000V p-p 1.5%

DC -50V ~ -600V DC 3%

•ERROR type: 1. if supply is GND, density will be extremely low.

2.if supply is floating (for insecure terminal contact), density will be down so slightly that it is impossible to make out with naked eyes.

6)Developing Voltage : Deve AC+DC(-)

•Function: voltage that supplies toner to Developing Roller

•Output voltage: AC 250V ~ 1650Vp-p 1.5% (supply voltage is connected to ZENER Diode 350V)

DC -50V ~ -600V DC 3%

•ERROR type: 1. if Deve is GND, density will be extremely down.

2.if Deve is floating (for insecure terminal contact), density will be extremely down.

2.2.3 CRUM

The CLP-310N engine will be equipped with electronics that can read and write data into NVRAMs otherwise known as CRUMs that reside within 1) C, M, Y, K Toner cartridges.

The CRUM has a company ID, and electronics logo.

The toner CRUM also identifies the type of toner cartridge (Standard or High Capacity). The CRUMs contain fixed data such as the low warning point, specified life point, and hard stop point (on toner)

and also store the current life count (pages count, pixels count, images count) and % of usage (gas gauge) data.

■ In the case of Refill Toner Install

1)Perception of Refill Cartridge (when power is on or the cover is closed) End of Life / life span data initialization -> judge to be Refill Cartridge

End of Life / life exhausted (simple refill) -> stop printing caused by life exhaustion

2)Operating

It is impossible to control appropriate development parameters, for there s no toner specification data. It runs with the setting of default development parameter. (Image quality will be degraded, for the lack of appropriate respond to the change of time and environment.)

■ Process after CRU life expiration

1)Record the information of End of Life.

2)Clear some information of Operation Area.

-> Supplier/Model Name/MFC date/Serial Number (Manufacture Information)

-> Let cartridge refiller initialize manufacture information and life span information.

2.3 S/W Structure and Descriptions

2.3.1 Architecture

The belt CRUM interface board is a transmission belt CRUM interface board of the photoelectric Dry Color Laser Printer, mounted on the printer body, making it possible to physically combine the body and the belt CRUM board.

Printer Driver

Language Monitor

Status Monitor

2.3.2 Language Monitor

Language Monitor is a part of the Printer Driver and the Windows Spool System. The main roll of the Language Monitor is that sends a job start message to the Status Monitor. Therefore the Status Monitor can start polling to get the printer status.

The second roll is that sends the job information such as User ID and Job ID to the Status Monitor and the Printer F/W. Hence the Status Monitor can stop polling because the Printer F/W informs the Status Monitor that printing job is complete.

2.3.3 Status Monitor

Status Monitor has no user interface. It shows only HTML help when any error occurs during printing jobs.
