Page 2 Specifications are subject to change without notice. Page 3 hereinafter referred to as "this machine" or "the printer". This information is vital to the service technician to maintain the high printing quality and performance of the printer. This manual consists of the following chapters Page 6 Drum Unit Page 8 Diagnostics Page 9: Regulation Laser Notice No.
The label shown below is attached in countries where it is required. This printer has a laser diode which emits invisible laser radiation in the Laser Unit. The Laser Unit should not be opened without disconnecting the two connectors connected with the AC power supply and laser unit.
Available only on Web page. Recycled paper Recycled paper Basis weight Caliper 0. Size Page Serial No. Page Unpacking Most parallel cables support bi-directional communication, but some might have an incompatible pin assignment or may not be IEEE compliant. The Parallel cable is not available for HL Do not use a Parallel interface cable that is longer than 6 feet 2 meters.
Check that the paper is flat in the tray and below the maximum paper mark. The opening screen will appear automatically. Page 40 5 Turn the printer power switch on. For Network shared printer users: Go to 3. Close the Chooser. Page 43 6 Double-click the Printer Driver Installer icon to install the printer driver. Follow the on- screen instructions. Click the Setup… button. Printing on Plain Paper, Recycled Paper or Transparency from the Paper Tray You can load plain paper, recycled paper or transparency into the paper tray.
If paper is loaded into the paper tray, the printer automatically feeds paper sheet by sheet and ejects the printed page into the output tray. Repeat for each page that you want to print. Stacking the printed transparency may cause a paper jam or the transparency to curl.
This damage is not covered under any Brother warranty or service agreement. Do not use bond paper. When printing on both sides of the paper, follow the steps below; From the Advanced tab choose the Manual Duplex printing mode, and from the Basic tab choose the Paper Source to be Auto Select or Tray1.
If you print 10 pages on 5 sheets of paper, it will print page 2 then page 1 on the first sheet of paper. Pressing the Go button wakes up the printer from Sleep mode to Warming up mode.
After warming up, the printer will be ready state. We recommend that you obtain a new drum unit to replace the current one. The Drum LED alternates turning on for 2 seconds and off for 3 seconds alternately. The printer will print a test page. The printer will print the current printer settings. While the CPU is driven with a clock frequency of The transmission speed is 12Mbps.
It is for the normal receipt and dual direction communication nibble mode, byte mode, ECP mode. Page 1. The regulated output and the production code of each power supply are listed below; Regist front actuator Pinch roller Separation roller Pinch roller The following graph shows the number of printable pages in the case of A4 printing.
The problem such as toner leak or image defect may occur when low-duty printing is continued for a long time. The toner used for the printer has a property that print density is light first and gradually darker in the course of usage. The charge is generated by ionization of the corona wire, which has a DC bias from the high-voltage power supply applied to it.
The flow of the ion charge is controlled by the grid to ensure it is distributed evenly on the drum surface. The laser beams reflected by the reflection mirror go straight toward the exposure drum below it, then expose the exposure drum.
The area exposed to the laser beam is the image to be printed. The surface potential of the exposed area is reduced, forming the electrostatic image to be printed. The negative charge applied to the paper causes the positively charged toner to leave the drum, and adhere to the paper.

Ball Confidential Page Guidelines For Lead Free Solder Relatively poor wettability, rough surface bumps are likely to be formed , and solder dragging Poor solder elevation Poor thermal conductivity and heat resistant difficult to melt 2.
Compositon Manufacturer Origin Soldering irons When soldering is performed manually using lead-free solder, a soldering iron that has little reduction in its temperature needs to be used.
This refers to a soldering iron that has a smaller degree of decrease in the temperature at the soldering iron's tip, such as when the soldering iron is applied to the base metal or solder is supplied, and the temperature is soon returned to the specified temperature. The printer should be used only in a clean, dust-free environment with adequate ventilation.
We recommend that you replace the drum unit with a new one before there is a noticeable deterioration in the print quality. If you have questions, call your local waste disposal office. Page Fig. Hold the cartridge level with both hands and gently rock it from side to side five or six times to spread the toner evenly inside the cartridge. If you put it in properly, the lock lever will lift automatically. When you replace the toner cartridge or the drum unit, make sure you clean the inside of the printer.
If printed pages are stained with toner, clean the inside of the printer with a dry soft cloth. If you do not, printed pages may have a vertical stripe. Close the front cover of the printer. Plug in the power cord, and then turn on the power switch. If toner scatters and your hands or cloths get dirty, immediately wipe or wash it off with cold water. The upper limit value is different between the starter toner cartridge and standard one.
