Power SourceFor 115 VAC printers, do not apply more than 127 volts RMS between the supply conductors orbetween either supply conductor and ground. For 230 VAC printers, do not apply more than254 volts RMS between the supply conductors or between either supply conductor and ground.Use only the specified power cord and connector. Only qualified service technician should beusing this Service Documentation to perform the services.

Plug the three-wire power cord (with grounding prong) into a grounded AC outlet only. If neces-sary, contact a licensed electrician to install a properly grounded outlet. If the product loses itsground connection, contact with conductive parts may cause an electrical shock. A protectiveground connection by way of the grounding conductor in the power cord is essential for safeoperation.

Disconnecting PowerWARNING

Turning the power OFF using the power switch does not completely de-energize theprinter. You must also disconnect the power cord from the printers AC inlet. Disconnectthe power cord by pulling the plug, not the cord.It is also important that sufficient time is allowed for printer shutdown prior to unplug-ging the power cord from the printer or power source. This can be determined by check-ing the Control Panel display, after turning the printer power Off, and waiting until theLCD display shuts down.Disconnect the power cord in the following cases:

if the power cord or plug is frayed or otherwise damaged, if any liquid or foreign material is spilled into the product, if the printer is exposed to any excess moisture, if the printer is dropped or damaged, if you suspect that the product needs servicing or repair, whenever you clean the product.

Phaser 7760 Printer Introduction and OverviewThe Phaser 7760 Color Laser Printer uses a ROS laser with an electrophotographic four-colorYellow Magenta Cyan Black (YMCK) tandem architecture. A finisher with stacking, stapling,punching, and booklet making features is available with the Phaser 7760 per selected model.

The Phaser 7760 is an A3 size, tandem laser color printer, which can print at 35 pages perminute (ppm) color and 45 ppm monochrome. The maximum print resolution are 1200 dpi x1200 dpi. Input trays can support up to 5 trays with 2500-Sheet High-Capacity Feeder or 1500-Sheet High-Capacity Feeder.

The Phaser 7760 configurations support 10baseTX, 100baseTX, and 1000baseTX Ethernetwith an RJ45 connector on the motherboard. USB 2.0 connection is provided as a standard.

Adobe PostScript 3 and PCL5c fonts are supported for the Phaser 7760.

EPA ENERGY STAR compliance is certified for the Phaser 7760. After a predefined period oftime since its last activity, the Phaser 7760 will enter a power saver standby mode in which theprinter systems are shut down as required to comply with ENERGY STAR. Any communica-tions interface will remain active and will have the ability to wake the printer up.

Service Call ProceduresService StrategyThe service strategy for this printer is to perform any applicable actions before attempting torepair any problems. Some problems will be corrected by this strategy without the need to diag-nose them. The Repair Analysis Procedures (RAPs) will be used for any remaining problems.

Problems that occur in the Basic Printer mode will be repaired before problems that occurwhen using the accessories.

Image Quality problems should be repaired after all other problems are repaired.

Service Call ProceduresThe Service Call Procedures are a guide for performing any service on this machine. The pro-cedures are designed to be used with the Service Manual. These procedures are to be usedfor every service call. It is recommended that you start at the appropriate troubleshooting pro-cedure and proceed from there. When servicing the printer, always follow the safety measuresdetailed in the Service Safety Summary.

Step 1: Identify the Problem1. Verify the problem reported by the customer.2. Check for any error codes and write them down.3. If the printer is capable of printing, print normal customer prints and service test prints to:

Make note of any print-quality problems in the test prints. Make note of any mechanical or electrical abnormalities present. Make note of any unusual noise or smell coming from the printer while printing.

4. Print a Usage Profile, if the printer is able to print and/or view the fault history under theService Tools menu.

5. Verify the AC input power supply is within proper specifications by measuring the voltageat the electric outlet while the printer is running.

Step 2: Inspect and Clean the Printer1. Turn the printer power Off and disconnect the AC power cord from the wall outlet.2. Verify the power cord is free from damage and is connected properly.3. Remove the Imaging Units and protect them from light.4. Clean and inspect the printer interior and remove any foreign objects, dust or loose toner.

NOTE: Use only a Toner Type II Vacuum.Do not use solvents or chemical cleaners.Do not use any type of oil or lubricant on printer parts.Do not use compressed air.

5. Clean all rubber rollers with a lint-free cloth, dampered slightly with cold water and milddetergent.

6. Inspect the interior of the printer for damaged wires, loose connectors, toner leakage, anddamaged or obviously worn parts.

Part 3: Find the Cause of the Problem1. Use the Error Messages and Chain Links Troubleshooting procedures to find the cause of

the problem if an error code is reported.

2. Use the Service Diagnostics to check 3. Use the Wiring Diagrams and Plug/J

readings at various test points as instrStep 4: Correct the Problem1. Use the Parts List to locate a part num2. Use the Repairs procedures to replaceStep 5: Final Check1. Test the printer to be sure you have c

tional problems present.2. Perform RIP procedures.

Items)ProcedurePerform the following procedure whenever you check, service, or repair a printer. Cleaning theprinter, as outlined in the following steps, assures proper operation of the printer and reducesthe probability of having to service the printer in the future.

The frequency of use and the type of paper a customer prints on determines how critical andhow often cleaning the machine is necessary. Record the number of sheets printed.

1. Clean the ADC Sensor (PL 1.3) on every call. 2. Compare the components in Table 1 with % life remaining.3. Perform the Service Actions for any High Frequency Service Item (HFSI) counters that

are over threshold or approaching the threshold. Using the customer's output volumenumbers (high, medium, or low volume), evaluate which HFSI actions should be accom-plished now to avoid an additional service call in the near future.
