Installation​

The cash drawer is equipped with a standard 6-pin RJ12 plug for direct connection to any EPSON POS printer or Epson-compatible POS equipment. When the receipt finishes printing, the printer automatically opens the drawer.

How to open the drawer​

The drawer can be opened in three ways:

  1. With the key included in the set.
  2. Emergency opening — using the lever located underneath the device.
  3. Electronically — from the cash register, after the drawer has been connected with the RJ12 cable.
warning

To reduce the risk of damaging or breaking the key, avoid leaving it in the lock during normal operation.

Removing the drawer​

Open the drawer and remove the plastic tray for coins and banknotes. Pull the drawer out as far as it will go, tilt the front edge of the drawer upwards, and pull the drawer out at an angle.

Maintenance​

The cash drawer slides should be cleaned and lubricated periodically. The frequency depends on usage and environment, but the typical recommended interval is every three months.

  1. Using a dry, lint-free cloth, wipe off old grease and debris from the inner and outer guides. Do not use water or any liquid cleaners.
  2. With a clean applicator, apply a thin layer of lithium-based bearing grease to the inner and outer guides.
  3. Slide the guides back and forth several times to coat the polyurethane rollers properly and distribute the lubricant evenly.

Frequently asked questions​

How do I open the HD-KER35 cash drawer?
The lock has to be in the open position first — when it is locked, the drawer cannot be opened and electronic pulses are ignored. With the lock open there are three methods: manually, by turning the key one more position past 'open' until the latch releases; electronically, when a fiscal printer or cash register issues the open-drawer pulse over the RJ12 cable; or in an emergency, using the lever underneath the housing.
Which cash registers and fiscal printers is the HD-KER35 compatible with?
The drawer has a standard 6-pin RJ12 connector and a 6/12 V solenoid, which is the most common POS standard. It connects directly to any EPSON POS printer or Epson-compatible device that issues the open-drawer pulse. Some legacy devices use a different pinout — check the device specification before ordering, or contact us with the model name and we will confirm compatibility.
Will the HD-KER35 work with a Novitus cash register?
No. The HD-KER35 is a passive drawer — the cash register supplies the solenoid pulse. Novitus cash registers require an active drawer with its own power supply and controller, so the two designs are not compatible.
What should I do if the drawer does not open from the fiscal device?
First confirm the lock is in the open position — when locked, electronic pulses are ignored by design. Then check that the open-drawer command is enabled in the cash register / fiscal printer software (the command name varies by vendor) and that the RJ12 cable is firmly seated. If it still does not open, use the key to open it manually and contact support.
Can the coin and banknote compartments be adjusted or removed?
Yes. The drawer has four banknote compartments with spring clips and eight coin compartments. The coin inserts can be dismantled or freely rearranged to suit your denominations, and the coin compartment can be lifted out completely for emptying.
Which mounting bracket fits the HD-KER35?
The HD-KER35 is designed to be used with the dedicated HD-MB35 mounting bracket, which fixes the drawer securely and space-efficiently under the counter.
