Safety warnings

Modifications not authorized by hp

HP MFPs are renowned for their high reliability. This reliability is achieved through high-quality design and a solid service network.

MFP design is a highly complicated and delicate process where numerous mechanical, physical, and electrical aspects have to be taken into consideration, with the aim of arriving at proper tolerances and safety factors. For this reason, unauthorized modifications involve a high risk of degradation in performance and safety. Such modifications are therefore strictly prohibited. the points listed below are not exhaustive, but they illustrate the reasoning behind this policy.

WARNING: Prohibited actions

Safety

● Using any cables or power cord not specified by HP.

● Using any fuse or thermostat not specified by HP.

● Safety will not be assured, leading to a risk of fire

and injury.

● Disabling fuse functions or bridging fuse terminals

with wire, metal clips, solder or similar object.

ENWW Safety warnings 3

Page 12

WARNING: Prohibited actions

● Disabling relay functions (such as wedging paper

between relay contacts).

● Disabling safety functions (interlocks, safety circuits,

and so forth) Safety will not be assured, leading to a risk of fire and injury.

● Making any modification to the MFP unless

instructed by HP.

● Using parts not specified by HP.

Checkpoints when performing on-site service

HP MFPs are extensively tested before shipping, to ensure that all applicable safety standards are met, in order to protect the customer and customer engineer (hereafter called the CE) from the risk of injury. However, in daily use, any electrical equipment may be subject to parts wear and eventual failure. In order to maintain safety and reliability, the CE must perform regular safety checks.

Power supply

WARNING: Wall outlet

● Check that mains voltage is as specified. Plug the

power cord into the dedicated wall outlet with a capacity greater than the maximum power consumption.

● If excessive current flows in the wall outlet, fire may

result.

● If two or more power cords can be plugged into the

wall outlet, the total load must not exceed the rating of the wall outlet.

● If excessive current flows in the wall outlet, fire may

result.

WARNING: Power plug and cord

● Make sure the power cord is plugged in the wall

outlet securely. Contact problems may lead to increased resistance,

overheating, and the risk of fire.

● Check whether the power cord is damaged. Check

whether the sheath is damaged. If the power plug, cord, or sheath is damaged,

replace with a new power cord (with plugs on both ends) specified by HP. Using the damaged power cord may result in fire or electric shock.

● When using the power cord (inlet type) that came

with this MFP, be sure to observe the following precautions:

a Make sure the MFP-side power plug is securely

inserted in the socket on the rear panel of the MFP. Secure the cord with a fixture properly.

b If the power cord or sheath is damaged, replace

with a new power cord (with plugs on both ends) specified by HP. If the power cord (inlet type) is not connected to the MFP securely, a contact problem may lead to increased resistance, overheating, and risk of fire.

Safety

ENWW Safety warnings 5

Page 14

WARNING: Power plug and cord

Check whether the power cord is not stepped on or

●

pinched by a table and so on.

● Overheating may occur there, leading to a risk of

fire.

● Do not bundle or tie the power cord.

Overheating may occur there, leading to a risk of fire.

● Check whether dust is collected around the power

plug and wall outlet. Using the power plug and wall outlet without

removing dust may result in fire.

● Do not insert the power plug into the wall outlet with

a wet hand. The risk of electric shock exists.

● When unplugging the power cord, grasp the plug,

not the cable. The cable may be broken, leading to a risk of fire

and electric shock.

WARNING: Wiring

● Never use multi-plug adapters to plug multiple power

cords in the same outlet. If used, the risk of fire exists.

● When an extension cord is required, use the

specified type. Current that can flow in the extension cord is limited,

so using a too long extension cord may result in fire. Do not use an extension cable reel with the cable

taken up. Fire may result.

6Safety ENWW

WARNING: Ground lead

● Check whether the MFP is grounded properly.

If current leakage occurs in an ungrounded MFP, you may suffer electric shock while operating the MFP. Connect the ground lead to one of the following points:

a Ground terminal of wall outlet b Ground terminal for which Class D work has been

done

● Pay attention to the point to which the ground lead is

connected. Connecting the ground lead to an improper point

such as the points listed below results in a risk of explosion and electric shock:

a Gas pipe (A risk of explosion or fire exists.) b Lightning rod (A risk of electric shock or fire

exists.)

c Telephone line ground (A risk of electric shock or

fire exists in the case of lightning.)

d Water pipe or faucet (It may include a plastic

portion.)

Safety

Protection by software

The output voltage from TH1 (fuser temperature sensor 1) is read by the CPU. If this voltage is abnormal, L2 (fuser heater lamp 1), L3 (fuser heater lamp 2), L4 (fuser heater lamp 3), and RL1 (main relay) are turned off.

CAUTION Do not change the gap between the roller and TH1. When replacing TH1, check

the specified mounting dimensions. The RL1 function must not be deactivated under any circumstances.

Protection by the hardware circuit

The output voltages from TH1 and TH2 (fuser temperature sensors) are compared with the abnormality judgment reference value in the comparator circuit. If the output voltage from TH1 or TH2 exceeds the reference value, L2 (fuser heater lamp 1), L3 (fuser heater lamp 2), L4 (fuser heater lamp 3), and RL1 (main relay) are turned off in hardware means.

CAUTION Periodically check the TH2 face contacting the roller, and replace TH2 if any

abnormality is detected.

Since theTH1 (fuser temperature sensor) face does not contact the roller, check the distance from the roller and the sensor orientation if any abnormality is detected.

The RL1 function must not be deactivated under any circumstances.

concentration patch formed on the drum to determine the toner concentration. Against image excessive density, image blur, and toner scattering in all tone areas, the setting should be made by shifting the threshold of black color to the positive side.

Against insufficient density in all tone areas, shift to the negative side.

• Standard -10: The image becomes darker.

• Standard +10: The image becomes lighter.

• Standard + 20: The image becomes far lighter.

Note There are three DIP

switches to change the image density: 5-0/1 (toner concentration threshold, 5- 2/3 (laser PWM), and 23-2/3 (toner density of developer). The priority of order of these adjustments are as follows: (1) Laser PWM (2) Toner density of developer (3) Toner concentration threshold

*8 Image density selection (laser PWM) for

MFP These bits set image write laser PWM.

Against excessive density of 100 percent black color, thick letters and lines, and excessive toner consumption, the setting should be made by selecting

light. In the opposite case, select dark.

● <Error message2>

A datum with potential not to function non-image-area-erase is found. Please confirm “Adjustment - “3-6 mode columns of the Service Manual.

● <Countermeasure2>

If you use the non-original erasure function relatively infrequently, you can use the MFP in its present installation environment.

If, however, you copy originals that have a dark background fairly frequently, move the MFP to a dark location and facing a direction such that external light does not get into it, then carry out the installation survey once again. In this case, if there is a bright light source, such as a fluorescent light, directly above the MFP, reconsider the installation location and direction, or take steps to block off the light from the light source (by using a cover, for example), then carry out the installation survey once again.
