J-2101
Konica Minolta J-2101 on laser printer: transfer jam code
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
Jam code J-2101 (along with J-3102 and J-3201) on Konica Minolta AccurioPress systems indicates a transfer-section paper jam when printing on the front side of thin paper. Clear the sheet without turning power off and adjust [Transfer-Fuser JAM(1st)] in [Simple Setting].
Safety first
Stop and check this first
- Do not touch the left side part of the fixing unit or the glue tank unit when the side part or side cover is open to remove jammed paper, as high temperatures can cause burns.
- Do not turn off the Main or Sub power switch while clearing paper jams, never forcefully tilt Lever [M1], and do not put hands or arms between the main body and conveyance fixing unit or touch electrical connecting terminals.
Safe checks you can perform
- Follow the JAM Position and Illustration screens without turning off either power switch
- Verify paper condition, feed tray settings, and the Air Blow function in Paper Separation
- Adjust [Transfer-Fuser JAM(1st)] in order from [JAM Reduction +1] to [JAM Reduction +3]
Leave these tasks to a qualified professional
- Do not attempt this professional task: Professional removal of torn paper scraps and inspection of the Fusing Conveyance Unit
- Do not attempt this professional task: Service inspection of the transfer section and fixing unit for recurring J-2101 jams
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Professional removal of torn paper scraps and inspection of the Fusing Conveyance Unit
What they doIf torn scraps remain inside the paper path or Lever [M1] cannot be operated safely, the authorized service representative clears the conveyance path and checks the sensors.
They must show youthe removed paper scraps from the transfer path and smooth movement of the Fusing Conveyance Unit.
In writingthe J-2101 jam code serviced, the path inspection performed, and confirmation that all safety covers latch properly.
Service inspection of the transfer section and fixing unit for recurring J-2101 jams
What they doWhen user adjustments in [Transfer-Fuser JAM(1st)] (+1 to +3) and [Paper Separation] do not stop J-2101 jams, the service representative inspects the transfer and fixing assemblies.
They must show youa multi-page test run on thin paper without J-2101, J-3102, or J-3201 jam codes.
In writingthe transfer or fixing adjustments and any replaced components documented on the service report.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Follow the JAM Position and Illustration screens without turning off either power switch
- Who:
- Operator at the touch panel when jam code J-2101 occurs.
- How:
- Without turning off the Main or Sub power switch, check the location number on the [JAM Position] screen, press [Illustration] and [Next] to view the steps, open the indicated cover, remove the jammed sheet carefully without tearing it, and close the cover.
- Result that matters:
- All jammed locations are cleared and the touch panel returns to the [MACHINE] screen.
- If Lever [M1] tilts to the right and cannot pull out the Fusing Conveyance Unit:
- clear the jam in the paper feed inlet or output section first and never forcefully tilt Lever [M1].
- If the Stacker of Finisher FS-532 or FS-541 is locked when pulling it out or returning it:
- rotate Knob [FS8] of the Stacker to release the lock.
- Evidence to keep:
- Intact removed sheet with no torn scraps left inside and display returned to the [MACHINE] screen.

Verify paper condition, feed tray settings, and the Air Blow function in Paper Separation
- Who:
- Operator inspecting the feed tray after jam code J-2101.
- How:
- Confirm that the loaded paper is in appropriate condition without creases or folded corners, verify that the paper size and tray settings match the loaded stock, and check the air-blowing volume in [Paper Separation].
- Result that matters:
- Air is blown evenly onto the stack in the feed tray so sheets feed smoothly.
- If paper creases or folded corners cause fusing jams:
- adjust [Creases/Folded Corners] under [Simple Setting].
- If thin paper continues to jam in the transfer section with code J-2101:
- proceed to the [Transfer-Fuser JAM(1st)] adjustment.
- Evidence to keep:
- Confirmed tray paper settings and [Paper Separation] air volume for the loaded thin stock.

Adjust [Transfer-Fuser JAM(1st)] in order from [JAM Reduction +1] to [JAM Reduction +3]
- Who:
- Operator in the Paper Setting menu on the touch panel.
- How:
- Open [Paper Setting] > [Simple Setting] > [Transfer-Fuser JAM(1st)] and apply adjustments in order starting from [JAM Reduction +1] up to [JAM Reduction +3].
- Result that matters:
- Paper jams in the transfer section on the front side of thin paper (codes J-2101, J-3102, J-3201) are suppressed.
- If jams occur when printing on the back side of thin paper (codes J-2102, J-3104):
- adjust [Transfer-Fuser JAM(2nd)] while noting that a higher '+' setting may increase image loss at the lead edge.
- If J-2101 jams persist even at [JAM Reduction +3]:
- contact your authorized service representative without touching electrical terminals.
- Evidence to keep:
- Selected [JAM Reduction +1] to [+3] setting and thin-paper test print result.

What it means
According to the Konica Minolta AccurioPress 7136, 7136P, and 7120 User's Guide (2023 edition), jam code J-2101 (together with J-3102 and J-3201) identifies a paper jam occurring in the transfer section when printing mainly on the front side of thin paper, whereas J-2102 and J-3104 apply to the back side of thin paper. The touch panel displays the jam location on the [JAM Position] screen and provides [Transfer-Fuser JAM(1st)] under [Paper Setting] > [Simple Setting] to suppress recurrence. Other Konica Minolta models may use different jam codes, and J-2101 alone never proves an internal assembly is defective.

Symptoms and causes
Probable causes · in order
- Printing on the front side of thin paper without transfer jam reduction enabledCommon
When printing on the front side of thin paper, the lead edge can stall in the transfer section and trigger jam codes J-2101, J-3102, or J-3201 if [Transfer-Fuser JAM(1st)] has not been adjusted.

- Unsuitable paper condition, mismatched tray paper settings, or unadjusted air-blow separationPossible
The manual highlights inappropriate paper condition, incorrect paper size or tray settings, or unadjusted air volume in [Paper Separation] as common contributors to paper jams.
