Kolibri Rook has been developed to count up to 1,400 bills per minute, which makes it one of the fastest bill counters on the market. Therefore, to avoid jamming, mis-feeding or other errors such as HLF, Chn or dbL, it’s extremely important to use the proper bill loading method. For better results, it’s also recommended to not count more than 100 bills at a time. Kolibri recommends a 3-step loading technique as described below:

1. Square the bill stack. Place the bill stack almost perpendicular to the carrying handle with the bottom of the stack touching the bill guide plate.
2. Flip the bill stack towards the rear of the machine so the stack is now leaning against the bill guide plate.
3. Bill feeding will automatically begin.

Dirty sensors can cause false errors such as “EA”, “A”, “b”, “dbL”, and “HLF” errors, and may decrease the performance of your Kolibri Rook Currency Counter. It is suggested that the user performs daily maintenance on the unit to maintain top performance.

Needed Items:

• Microfiber cloth
• Bristle brush
• Compressed air
• Isopropyl alcohol

Steps:

1. Ensure the unit is turned off and unplugged.
2. Clean each sensor in the following order, checking after each step:
   a) Dust off with a microfiber cloth or bristle brush.
   b) Blow out dust with compressed air.
   c) Moisten a cotton swab with isopropyl alcohol and gently clean the sensors.

Sensor Locations:

• Hopper Sensor: At the top, where bills are loaded.
• Stacker Sensors: In the stacker pocket, where bills are stored after counting.
• Counting Sensors: Under the display panel (left and right, with upper and lower components).
• Stacker Sensor: Between the counting sensors.

Refer to section 5.1 of the Rook User Manual.

The feed gap of the unit is always properly adjusted before shipping to customers. Sometimes during the transportation or accidental jarring of the unit, the adjustment of the feed gap might be altered. The feed gap will also gradually increase over time with normal wear and tear. These conditions can lead to error (“dbL”, “Chn”, “HLF”) or bill jams. Please follow the steps below to re-adjust the feed gap. If your unit is operating normally,

1. Ensure the machine is off.
2. Locate the feed gap adjustment knob at the rear of the unit.
3. If multiple bills are being pulled (dbL errors), turn the knob clockwise (decrease gap) by ¼ turn. Test after each adjustment.
4. If bill jams occur at the input, turn the knob clockwise by 1/32 turn (11°), then test again.
5. Check the gap: Slide a bill between the bill guide plate and rollers. It should pass with slight resistance—enough to feel friction but not cause jamming.
6. Test with a stack of bills after each adjustment. Avoid over-adjusting as it may lead to further issues.
