SP-A310 Service & Parts Manual September 1996 +-’ Revision C-02 WARNING LABELS - i SAFETY INFORMATlON . ALL Areas INTERNAL LASER RADIATION Maximum radiation power: 8.8 x lo4 (W) Wavelength: 770-8 10 MI This is a Class Bib Laser Diode Assy. that has an invisible Laser Beam. The Print Head Unit is NOT A FIELD SERVICE ITEM. Therefore, the Print Head Unit should not be opened under any circumstances. U.S.A. Only LASER SAFETY This LBP printer is certified as a Class 1 laser product under the U.S. Department of Health and Human Services (DHHS) Radiation Performance Standard according to the Food, Drug and Cosmetic Act of 1990. This means that the LBP printer does not produce hazardous laser radiation. Since radiation emitted inside the LBP printer is completely confined within protective housing and external covers, the laser beam cannot escape from the LBP printer during any phase of user operation. CDRH REGULATIONS The Center for Devices and R&ological Health (CDRH) of the U.S. Food and Drug Administration implemented regulations for laser products on August 2, 1976. These regulations apply to laser products manufactured from August 1, 1976. Compliance is mandatory for products marketed in the United States. The label shown in the figure indicates compliance with the CDRH regulations and must be attached to laser products marketed in the United States-. CLASSIFICATION OF THE LASER PRODUCT This product is classified as a Class 1 Laser Product under the CDRH Regulations U.S.A.. CAUTION Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to manufacture’s instructions. ii . Denmark Only ADVARSEL!

I C A Caution 1 Opening the cover indicated by the Caution label below may expose you to harmful laser radiation which could cause damage or loss of eyesight. Do not Open the Cover when the power is on. iv PRECAUTIONS (1) Precautlbns Refer to D: DISASSEMBLY/ CLEANING for the Disassembly procedure. Be sure to unplug the printer befcre disassembling and cleauing. pczzi&q 1. When unplugging ccumec tors on the P.WI3.s themselves, always make sum the power is OFF first. 2. Always unplug conrxctors by holding the connector housing. Pulling on the power cord can lead to problems with poor contact. 3.Itisrec canmended that a body ground not be used when carrying out any trouble-shooting procedure. Be sure to ground DC lines to a ground test point on the P.W.B. pGiq (2) At Replacement/ Adjustment/ Cleaning l.BesuretohandletheFusingUnitcarefullyastheunitisstillhotforawhileafbertheprinteris stopped;t: 2.

Keep your hands. clothing, etc. well away from operating or rotating parts. 2. Never touch the temhals d electrical parts or high voltage parts. 3.Thisprinbuisusinganinvisiblelaserbeam.Topleventalaserbeamleak.theprintermaLesatri~ runtobesurethecoversarein@tion. HANDLING THE P.W.B. Observe the folIowing precautions when handling a P.W.B. with ICs. (1) During Transportation/ Storage i: 1. During transport and storage, P.WB.s should be kept incarductive bags or on mats and not taken out lmkss absolutely rEce.ssary. 2. P.WBs should be stored in a place where direct sunlight does not strike them. 3.Don0ttouch1Ctermin&withyourhands. (2) At Replacement 1. Before removing connectors from a P.WB.. make sure the printer has been ~npluggcd 2. When P.WB.s are taken out of their conductive bags or off their mats, hold them by t&sir edges to avoid touching the term&Is or the patterned surfaces. 3.BeforeinstallingumnectcrsonaP.WB..makesuretheprinterhasbeenunplugged. (3) At Inspection 1. Avoid checking a P.WB. with testers; instead, use operating pa.tQ of the printer. mdicatrx ktrps, and other means to evaluate operational umditions. 2. Be careful not to short-circuit IC terminals when using metal instruments or screws. 3. If it is necessary to touch elements on the P.W.B. with your hand, make sure your body is properly 5&d V CONTENTS A: PRODUCT INSTALLATION 1.

Duplex (Option) - When the duplex unit is mounted on the printer, t&e exit roller is co-ted to the switchback motor (MC) by way of the coupling lever and gear. 1. When the printing cycle is completed for l-sided printing, the paper, moving past the exit sensor, is fed out of the printer by the exit roller. 2. When the printing cycle is completed for the front side in 24ded printing, the paper is fed towards the exit by the exit roller until it moves past the exit sensor. When the paper move3 past the exit sensor, the switchback motor (M6) is turned backward feeding the paper back to the duplex paper take-up area The transport motor (M5) then transports the paper up to the registration roller. Skew in paper is corrected by the registration senscx ad then the registration roller feeds the paper to the image transfer section far printing to the back side.

Fusing Unit malfunction l%e printer considers that there is a fusing malfunction when any of the following four conditions is detected. 1. The temperahue of the upper fusing roller (as measured withtbethermistor)issuchthatthechangein the thermistor voltage is O.lV or less over a period between 12 sec. to 30 sec. after warm-up has star&xi (with the fusing rollff temperature being 16OT or less). 2. The fusing roller temperature does not exceed l!WC for a 120 sec. pericd after warm-up has started. 3. The fusing roller temperature becanes less than 14UT in t.be standby state. 4. ‘Ihe fusing roller temperature become less than 1WC during a printing cycle. 5. The fusing roller temperature remains more than 24OT while the fusing temperature is being controlled. 13. Laser malfunction T%e laser output level is adjusted befoxe printing. A laser fault is detected if the output level cannot be adjusted to the specSed value. r 1-4.
