HP Designjet L25500 Printer Series - Safety precautions

Before using your printer, read the following safety precautions to make sure you use the equipment safely.

General safety guidelines

  • Refer to installation instructions before connecting the printer to the supply.

  • There are no operator-serviceable parts inside the printer. Refer servicing to qualified service personnel.

  • Turn off the printer, unplug both power cords from the power outlets, and call your service representative in any of the following cases:

    • The power cord or plug is damaged.

    • Liquid has entered the printer.

    • There is smoke or an unusual smell coming from the printer.

    • The printer has been dropped or the drying or curing module damaged.

    • The printer's built-in Residual Current Circuit Breaker (Ground Fault Circuit Interrupter) has been repeatedly tripped.

    • Fuses have blown.

    • The printer is not operating normally.

  • Turn off the printer and unplug both power cords from the power outlets in either of the following cases:

    • During a thunderstorm

    • During a power failure

Electrical shock hazard

The drying and curing modules operate at hazardous voltages capable of causing death or serious personal injury.

The printer uses two power cords. Unplug both power cords before servicing the printer. The printer must be connected to earthed mains outlets only.

To avoid the risk of electric shock:

  • Do not attempt to dismantle the drying and curing modules or the electrical control cabinet.

  • Do not remove or open any other closed system covers or plugs.

  • Do not insert objects through slots in the printer.

A blown fuse may indicate malfunctioning electrical circuits within the system. Call your service representative, and do not attempt to replace the fuse yourself.

Heat hazard

The drying and curing subsystems of the printer operate at high temperatures and can cause burns if touched. To avoid personal injury, take the following precautions.

  • Do not touch the internal enclosures of the printer's drying and curing modules. Even after opening the window latch that disconnects drying and curing power, the internal surfaces could be hot.

  • Take special care when accessing the substrate path.

Fire hazard

The drying and curing subsystems of the printer operate at high temperatures. Call your service representative if the printer's built-in Residual Current Circuit Breaker (Ground Fault Circuit Interrupter) is repeatedly tripped.

To avoid the risk of fire, take the following precautions.

  • Use the power supply voltage specified on the nameplate.

  • Connect the power cords to dedicated lines, each protected by a branch circuit breaker according to the rating of the wall socket. Do not use a power strip (relocatable power tap) to connect both power cords.

  • Use only the power cords supplied by HP with the printer. Do not use a damaged power cord. Do not use the power cords with other products.

  • Do not insert objects through slots in the printer.

  • Take care not to spill liquid on the printer.

  • Do not use aerosol products that contain flammable gases inside or around the printer.

  • Do not block or cover the openings of the printer.

  • Do not attempt to dismantle the drying or curing module, or the electrical control cabinet.

  • Load substrates that can be used at an operating temperature of up to 125°C (257°F), and have auto-ignition temperatures above 250°C (482°F).

Mechanical hazard

The printer has moving parts that could cause injury. To avoid personal injury, take the following precautions when working close to the printer.

  • Keep your clothing and all parts of your body away from the printer's moving parts.

  • Avoid wearing necklaces, bracelets and other hanging objects.

  • If your hair is long, try to secure it so that it will not fall into the printer.

  • Take care that sleeves or gloves do not get caught in the printer's moving parts.

  • Avoid standing close to the fans, which could cause injury and could also affect print quality (by obstructing the air flow).

  • Do not touch gears or moving rolls during printing.

Heavy substrate hazard

Special care must be taken to avoid personal injury when handling heavy substrates.

  • Handling heavy substrate rolls may require more than one person. Care must be taken to avoid back strain and/or injury.

  • Consider using a forklift, pallet truck or other handling equipment.

  • When handling heavy substrate rolls, wear personal protective equipment including boots and gloves.

Ink handling

Your printer does not use solvent inks and does not have the traditional problems associated with them. However, HP recommends that you wear gloves when handling ink system components.

Warning labels

Label
Explanation
Risk of burns. Do not touch the internal enclosures of drying and curing modules of the printer.
Risk of burns. Do not touch the drying enclosure of the printer. Even after opening the window latch, which disconnects the power to the drying and curing modules, the internal surfaces could be hot.
Electric shock hazard. The printer has two input power cords. A voltage is still present in the drying and curing modules after the main switch is turned off. There are no operator-serviceable parts inside the printer. Refer servicing to qualified service personnel. Disconnect all power cords before servicing.
See installation instructions before connecting to the supply. Ensure that the input voltage is within the printer's rated voltage range. The printer requires two dedicated lines, each protected by a branch circuit breaker according to the rating of the wall socket outlet. Use only earthed mains outlets and the power cords supplied by HP with the printer.
Risk of trapped hands. Do not push the roll while loading. Lift the loading table to ease the spindle into the printer.
Risk of trapped fingers. Do not touch spindle gears while moving.
Do not put objects on top of the printer. Do not cover the fans.
You are recommended to wear gloves when handling ink cartridges, printhead cleaning cartridges and the printhead cleaning container.
