Handling Paper Discusses paper selection and paper handling: • Types and sizes of paper you can use with this printer, including envelopes and transparencies • Ensuring that both the software program and the printer have compatible paper size settings • Tips on handling print media • Adjusting the paper tray to fit a different paper size • Feeding paper manually Paper Types and Sizes This printer can print on a variety of common office papers in addition to standard photocopier bond.
This printer can print on a wide range of paper sizes, but the size is limited when using paper trays. • When using a paper tray, the size is: Paper size (physical) Dimensions A4 (European letter size) A5 Letter (US letter size) Executive 210 x 297 mm 148 x 210 mm 8.5 x 11 in 7.25 x 10.5 in • When using the manual feed slot, the size is: Minimum: 100 mm wide x 148 mm long (3.94 x 5.81 inches) Maximum: 216 mm wide x 360 mm long (8.5 x 14.
Although this printer can print on any sheet within the limits stated above, printing area and margin calculations are based on several paper sizes as shown in the table below. Use the control panel to change the supported paper size. Paper size (logical) Dimensions A4 A5 Letter Legal Executive Envelope COM-10 Envelope Monarch Envelope C5 Envelope DL Envelope B5 210 x 297 mm 148 x 210 mm 8.5 x 11 inches 8.5 x 14 inches 7.25 x 10.5 inches 4 1/8 x 9.5 inches 3 7/8 x 7.
Preprinted Sheets In general, you can safely print on preprinted sheets such as letterhead. However, letterhead with thermographic (raised) printing, embossing, or foil stamping may not work well. The forces used to create these effects (heat and/or pressure) are also used in the printer’s fuser unit. For this reason, the fuser unit may damage the preprinted image. Load preprinted paper with the printed side facing down in the paper tray.
Envelopes This printer prints well on envelopes if you carefully follow these guidelines: • Use envelopes made of paper in 75 to 105 g/m2 (20 to 28 pound) weight. Printing with envelopes made of paper thinner than this weight may produce wrinkles thus causing decrease in print quality. • Be sure to set up the rear stacker (or that of the duplex unit when your printer has the duplex unit) so that envelopes are ejected straight out the back to minimize curl.
Labels This printer prints well on labels if you carefully follow these guidelines: • Be careful to use labels under normal operating conditions. Labels are sensitive to temperature and humidity. • Use the rear stacker (or that of the duplex unit when your printer has the duplex unit) so that labels are ejected straight out the back to minimize curl. • Use only labels without backing sheets exposed in the printable area. Labels mounted separately on a backing sheet tend to slip, resulting in crocked print.
2. Change the setting of the paper size indicator. Lift the right end of the indicator and slide it to the desired position, that is, adjust the triangle mark to A4, A5, LTR, or EXE engraved on the tray. 3. Remove the rear paper guide from the tray.

Feeding Paper Manually The multi-function of this printer has a slot that allows you to feed sheets manually one by one. Use the manual feed slot to print a document on a different type of paper without unloading your regular paper from the paper tray. You also use manual feed for printing envelopes, overhead transparencies, and labels. You can also use the manual feed slot built in the printer. The procedure is the same.
Setting Up the Rear Stacker This printer has a rear stacker that allows you to eject sheets straight out the back to minimize curl. Use the rear stacker to print envelopes, overhead transparencies, and labels. For the rear stacker of an optional duplex unit, refer to its manual. To use the rear stacker, follow these steps: 1. Open the rear stacker. Pull the projections at the top of the stacker. 2. Remove the paper support from inside the stacker. Paper support 3. Set the paper support in position.
Printing on Nonstandard Size Paper and on Envelopes Most of the control over printing on nonstandard size paper must come from your software program. Programs handle page size specifications in many different ways. This section provides tips on feeding and using non standard paper with your printer. Considerations on Paper Size The following considerations apply: • For envelopes and other nonstandard paper sizes, use the manual feed slot.
Page Orientation Figure 2-4 illustrates the two orientations and shows the relationship between the loaded paper and the resulting printout. This relationship is important if you want to print on letterhead. In portrait orientation, place the letterhead toward you and face down in the paper tray. In landscape orientation, place the letterhead against the right frame of the tray and face down.
CHAPTER 3 Enhancing and Customizing the Printer This chapter explains the following ways to enhance or customize your printer: • Add RAM up to a total of 67 megabytes. • Expand the fonts available from the printer. • Add an additional interface. • Add a different size of paper tray. • Add a paper feeder as the second paper source. • Add a duplex unit as the two-sided printing mechanism. You can order these options separately. Contact your dealer for information on the options that are available.
☞ There are two memory expansion slots available. The expansion card can have so called SIMMs (up to two times 32 MB). Together with the controller's board fixed memory of 3MB, these expansion options offer a range of RAM from 3 (no SIMM installed) to 67 MB (both SIMM slots equipped with 32 MB).

Cleaning the Precharger Wire The precharger wire is on the print unit. Normally you should not need to clean this wire. However, the following conditions may indicate that the wire needs cleaning: • Your printed pages have dark vertical lines, or the print density is uneven. • Cleaning the corona wire does not solve the problem. Use the cleaning brush supplied with the printer. This L-shaped tool has two cleaning pads: one for the precharger wire and the other for the corona wire inside the printer.
Repacking the Printer If you need to ship your printer or store it for an extended time, protect it by packing it in its original carton. Store the print unit separately from the printer. Do not remove the toner cartridge from the print unit. Cover the photoconductive drum to avoid exposing the drum to light, wrap the print unit and toner cartridge with a protective material, and store it in a safe place. To protect the printer from moisture, place it in the plastic bag it was shipped in.
CHAPTER 5 Solving Problems Although this printer is designed to be highly reliable, you may occasionally experience problems. The most common problems are paper jamming and poor print quality. This chapter helps you to identify the cause of the problem and suggests solutions. ☞ This chapter is divided into five sections: • Clearing Paper Jams. This section explains how to locate and clear paper jams. • Operational Problems. Start here if the printer doesn’t function properly.
☞ To clear a paper jam, follow these steps: Notice: Clear paper jams quickly to avoid problems with the fuser unit. Do not touch or scratch the green drum surface when clearing the paper jam. Be careful not to expose the drum to light for more than three minutes. Take special care when removing a jam from the transfer corona unit to avoid damage to the corona wire. 1.

Glossary Application software A program that performs a particular task on a computer. Examples are word processing, spreadsheet, and database programs. Baud The speed of data transmission measured in bits per second. Baud rates apply to data transmission through the printer’s serial interface. Baud is also called baud rate. For example, 1200 baud is approximately equal to 120 characters per second. Bit A binary digit, or bit, is the smallest unit of information in a computer’s memory.
Bitmapped font A font in which the character images are defined by bit maps. With bitmapped fonts, a separate set of definitions is required for each point size. For example, Times 10 point and Times 12 point are considered separate fonts. See also Scalable font. Configuration A combination of settings that allows your computer and printer to work together. Some of the necessary settings are in the computer or application software, while other settings are in the printer.
Ethernet A communication hardware for a high-speed network: developed by Xerox Corporation. Factory default The settings that are programmed into a printer at the factory. The printer uses these settings unless they are replaced by user selected settings entered from the control panel or through application software. Flow control See Serial protocol. Font A complete set of characters and symbols in one size, typeface, and style.
ISO symbol set ISO stands for “International Organization for Stanardization”. An ISO symbol set contains special international characters that replace the following twelve ASCII characters: #, $, @, [, \, ], ^, 9, {, |. }, and ~. ISO symbols sets are available for most European languages, Chinese, and Japanese. LocalTalk A protocol for an easy AppleTalk that connects devices and computers in a Macintosh system, developed by Apple Computer.
Page protect A printer feature that reserves a block of printer memory exclusively for text and graphics data. Page protect prevents memory overflow errors when printing very dense text or complex graphics. However, page protect also reduces the amount of printer memory available for downloadable fonts. Parallel interface A connection between the computer and printer in which data is transferred simultaneously through multiple wires.
Example: Printable area Nonprintable margins Printer driver A set of instructions in application software that translates formatting choices into printer commands. When installing the application, the user identifies the type of printer being used so the application knows which printer driver to use. Print unit A maintenance package consisting of the photoconductive drum, developing unit, toner, and drum cleaner. Reset Clears the print buffer and places the printer online.
Serial interface A connection between the computer and printer in which data is transmitted sequentially over a single wire. A serial interface is slower than a parallel interface, but it can send data over a much greater distance. The RS-232C interface is a type of serial interface. See also Parallel interface. Serial protocol A set of rules used by the computer and the printer to regulate the flow of data between them. Symbol set The set of characters used in a font.
