use high quali~ laserpaper to resolve their

problems.

CE ‘sActions if Paper Problems are Suspected:

1.Ensure aHigh QualityLaser paper istaken on site (Xerox 80 grm Premier); do NOT leave m car ovemi@t.

2. Take a copy of the paper spec guide (5002-1801) to @e to customer. Ensure your local office has a quan~ to use for this purpose. Does Paper meet Paper Spec’s Guide? Does

media come under the heading of “Papers likely to cause problems or papers to avoid”?

3, Ifpaper ia suspected use “HOWDiagram”to help isolate problem,

4. Keep customer involved at all times, explarnhow important paper is for correct operation of their printer.

5. Use HP LaserJW Reference Ouide (Knowu as Oreen Book) paper section for fiuther media

information. There is a paper suppliers list in this section that customer maywisb to try.

6. Show Paper Video to customer, inappropriate, this will help them better appreciate the

importance of paper when used in ~ LaserJet printers. (596 1-0712 PAL formst) or

(5961-071 1NTSCformat)

Factors that Contribute to paDerPath & Print C)ualitvProbIems:

*Does the media meet the Paper Spec’s outlined m Paper Spec Gnide(5002- 1801)? *Is the customers media m good contilon, damage~ bent, skew, wriukled or “Dog Eared”? *Are media haadling practices beiag observed (loading paper, removing Paper Jams)? *Has the media customer is having problem ever worked? * Is media berng conditioned before use?

* Check the follotig mthe printer operating entionment

- SunJightExposure.

- Clearriness

Media Likelv to tive Paner Related Drob]ems:

HP cannot stop customers using anypartiti paper, but certain paper will give more frequent paper jam or paper path problems. Some of these are:

*Paper too thin or too thick (see caliper inpaper spec ‘s)

*Extremely Shiney or Glossy media. * Recycledpaper that has not be spec ‘edfor LaserJetpn”nters. *Multi-patifom. *Media tkat is damaged, curled, wrinkled, ot of an irregrdar shape. *Papers that do not conform toA4, Letter, etc sues md may be loose or too tight in

The LaserJet Confidence Test Tool

WhatisJetTest

JetTest is a confidence test tool tie CE can use to quickly detetie communications

betweenthe PC andtheLaserJet. It alsoteststhe fimctionalityofthethe LaserJet. ~stest comes

on a bootable floppy disk and is very easy to use.

WhvUseJetTest

negates the customers application/sof~are asit isabootable disk.

*It

*It checks communications between PC andthe LaserJet or L2000. [1]

checks tie functionality of the LaserJet (i.e. Duplex, I/P source selection, etc)

*It

*It quickly helps CE determine if fault reported is a LaserJetproblem. *It reduces” Over-Delivery” of HP support services. *It will help to reduce the NFT rate of Formatter PCA’S. *JetTestwill not run if disk is NOT Write Protected.

Has CRC checking when disk is booting. (Virusprotection)

It is very easy to use.

How to RUNJtiTest

1.Install the Bootable disk inA: Drive of PCA

2. Power off fie PC, then on again or CTrl, Shift &DEL Keys together 3 .Takeapprox 1 minute to BOOT-up.

4.The J~EST screen will appear,then simpIy follow to menu driven screens and choose test you wish to run, number of copies, etc.

Note: The mouse will ody work ifthe PC has serial mouse, ifnot use TAB and/or arrow keys.

How to Obtaina Covv ofJetTmt

Interlock assy.

3. Print engine transformer.

4. Misskrg DC Voltage, replace DC Power Supply~otor Driver PCA.

The latch (FA2-5678-OOOCN)which holds down the uppermain body on the LHS had a small crackin it.

It was difficult to see the crackand printer appearsto

function correctly. On applying power it would intermittently give E~OR 12 or the printer would

not power up at all. This was caused by the motor

starting up and causing upper chassis to flex. Due to this movement (1 to 2mm), this was enough to trigger the interlock. When the interlock had operated, power is cut, motors stpped, frame returns to its correct posi tion, then power is reapplied. This scenario can thus repeat. Replace latck FA2-5678-OOOCN.

2686A/D - FAULTS WITH ERROR NUMBERS (Con’t)

2686D ERROR 12, paper not feeding correctlyfrom both I/P trays, it “Judders”, then Error12 occurs. Also

a BLANK page is emitted

from the printer.

ERROR’s 20,21, 22& 40

ERROR 50 Hard Fault

(S= note on below)

Traced to bad “Lid Switch” ie “DOOR OPEN”.

(Loss of +24v).

Error 20 (memory overflow) and Error 21 (print

ovemm) Usually caused by software due to the

following

CPU~ost sent to much Data to 2686. To clear press

continue.

Error 21...The formatter cannot catch-up with print the print engine.

Error 22 (Buffer Overflow) and Error 40 (line error).,

Usually caused by system configuration problems i.e.

Baud rate, parity, 7[8 bits, Xofioff/DTR, Normal settings: Baud rate -9600

Parity - None Bits

‘S 20.21, 22& 40.

See Servke Note 2686A-9

Normally caused by the following in order of preference:

L The 470hm resistor on Fuser Safe@ PCA blown.

(obtain 1/4 watt local~) or HP PIN is FF1-3872-OOOCN.(See Sfl 2686A-10).

2. Fuser Saf@ PCA.

3. AC Controller PCA.(new @pe has -040CN suffm).

4. Vibration in @anspo&g the 2686 causes Fuser

Bulb to rotate glass protrusion on fuser bulb to

point towards thermistor.

5. Fuser Bulb, should read 9/10 ohms. (known to

blow at 11 ohms).

6. Faulty or Dirty Thermistor.

Z Bad connections on the Fuser Saf@ or AC

8. Repbce The in Power Module assy.

9. Faul@ DC Power SuppfyMain Motor PCA.

10. Iffaultpersists replace Fuser Safety, AC

11. Check z~2686 is conjiguredfor 240volts?

N’otc Due to error messages being retained in memory for some time afte

power down it can fool the Service CE into believing the assy just replaced did not resolve the problem. Either do one of two things:

ERROR 53?

E~OR 60 & 61.

ERRORS 63, 65& 67

Possible causes-

1. Nohey AC Mains Power Supply. The 2686A’s are

more susceptabfe to AC mains disturbances than

perhaps other equipment ConnectAC Mains

Monitor. Check quality of mains supply.

2. InstallAC Controller who’s Pm ends in -040CN Suffa

3. Replace QI Triac.

4. Checkfor AC Voltages asper below:

PS/W Motor PCA @om Transformer.

These are:- 33, 12, 21volts on J501 connetir.

5, Check z~2686 is conjiguredfor 240v.

6. Noisv AC mains, instaU mains monitor.

Z See 2686A-10 Service Note.

8. Replace DC PS~ain Motir PCA.

9. Replace DC Controller PCA.

Replace ~ PCA

Replace Laser unit

Both these errors can be wused byfaulty W PCA ‘s.

Normally caused by LT PCA.

ERROR 67

ERROR 60, 65& 67

MISCELLANEOUS

ERROR’s 6X.

Cm be caused by very cold environmentsi.e

temperatures in office maybe falling very low over night. May give this problem only first thing in the morning, there on after will be OK all day.

Can be caused by atteinptkag to put to many fonts on one page

Especially Error’s 60,63 and 67 may be caused by

loose ubfing. If the cable are not securely fixed down the printer may exhibit these problems.
