Frequently Asked Questions - 408A MBM

How do I set up the MBM 408A for the first time?

Install the folding tables (Table 1 and Table 2) by inserting their plugs into the connectors. Connect the power cable to a grounded outlet (100-240VAC, 50/60Hz). Raise the paper ejection table and auxiliary table. Turn on the power switch; the touch panel will light up. Before use, ensure the power cord is fully unwound and the earth wire is properly grounded.

How can I adjust the fold position for standard paper?

After selecting the paper size and fold type, perform a test fold using the TEST key. If misalignment occurs, use the fine adjustment knobs on the control panel: press the +/- keys for fold 'a' or 'b' to move the stoppers. Alternatively, use the stopper fine adjustment knobs physically on the machine. Always re-test after adjustment.

What should I do if a paper jam occurs?

The machine will display an error code (e.g., E-05, E-20, E-70) and a message. Open the appropriate cover (safety cover, rear cover) and carefully remove the jammed paper. Close the cover and press the OK key (or error release button) to clear the error. If jams persist, clean the folding rollers and sensors, and ensure paper meets specifications.

How do I clean the folding rollers?

First, turn off and unplug the machine. Remove the rear cover and folding tables. Lower the roller setting lever to OFF, slide the upper roller left and remove it, then remove the lower roller similarly. Clean all four rollers with a cloth dampened with dedicated cleaner, rubbing firmly until no dirt remains. Reinstall in reverse order, ensuring the lever is returned to ON.

What does error code E-52 mean?

Error E-52 indicates double feed – two or more sheets were fed together. The double-fed paper will be ejected onto Folding Table 1 (inside the rear cover) without being folded. Open the rear cover, remove the paper, close it, and press the error release button. To prevent recurrence, fan out the paper stack thoroughly before loading.

Can I save custom fold patterns for later use?

Yes. For non-standard folds or non-standard paper sizes, you can memorize up to 20 patterns. After setting the fold parameters (a, b, speed), press the Gear key, then Fold Pattern Memory. Select a memory slot (M1–M12 or more) and press and hold the memory area for 3 seconds to save. To recall, press the Memory Fold key and choose the desired pattern.

How do I fold non-standard paper sizes?

Press the Non-standard Fold key, then Input Paper Length to enter the paper length manually. Select the nearest fold type and input dimensions 'a' and 'b' (fold positions) using the numeric keypad. Perform a test fold and adjust if needed using the fine adjustment knobs. Start continuous folding with START/STOP.

How can I change the folding speed?

On the main screen, use the - and + keys next to the speed indicator to adjust among 5 levels. For special modes, press and hold the speed area for 3 seconds to enter SPECIAL mode, which offers SP1 (silent), SP2 (thick paper), and SP3 (high speed for A4 or smaller).

How do I perform cross folding?

Cross folding is used to further fold paper that has already been single-folded (e.g., A3 double parallel fold to fit an envelope). Load the single-folded paper on the feed table, set auxiliary paper guides away from built-in guides, and adjust the paper feed auxiliary roller to hold down the folded edge. The amount of paper should be 30 sheets or fewer. Select the desired fold type on the touch panel.

What paper specifications are recommended for the 408A?

The machine accepts paper sizes from 3.5 in × 5.0 in to 11 in × 17 in (3.5×5.0 only for single fold). Paper weight should be 46.5–160 g/m² (up to 230 g/m² for single fold). Use high-quality, medium-quality, or woody paper. Avoid paper that is curled, wavy, or already folded. Even within specs, previously printed or heated paper may cause issues.

Simple line drawing of a stack of three sheets of paper (no text or symbols)

• Cross-folding is to further perform double parallel fold or letter fold on a sheet of paper folded already by single fold.
- This is good for folding A3 size stock which is already folded by double parallel fold but still will not fit into a standard size envelope.
* Paper that can be used for cross folding varies according to the conditions such as type of paper, paper size, paper with lateral grain, paper with vertical grain, temperature and humidity, printing conditions.

It may occur that lateral slanting is larger than normal folding or the corner of the crease is folded inward, but this is not caused by machine failure.

Caution!

Press along the single folded line of the paper with fingers.

The amount of paper loaded should be less than normal (30 sheets or fewer).

Auxiliary paper guides should be placed away from built-in paper guides, and the roller should hold down the single folded line by the first folding process.

Feed angle adjustment knob

If the folding position is slanted because the paper is cut at a slant or for other reasons, it can be adjusted using the slant adjustment knob.

Turn the slant adjustment knob to the right direction 1, if the lower side of the folded paper slants to the right. Turn the knob to the left to the direction 2 if the lower side slants to the left.

(The basic position of the knob is the center where the pin is aligned with the slot.)

Caution!

Check if there is any space between the paper guides and the paper.

In cases other than single fold, put the folded paper at Table 1 face down to make a ejection adjustment.

If paper is reset at the paper feed table, start slant adjustment over again.

After specific job is completed, return the slant adjustment knob to its basic position, i.e., center in the slot.

6. Maintenance Service, Inspection, Expendables

6-1 : Important points for maintenance service and inspection

6-2 : Usual maintenance service

Machine body

• If paper dust or dirt accumulates on the folding rollers, mechanical troubles may occur to the folding function. Therefore, place the machine cover over the machine when it is not in use.
• As for stains on the exterior parts, use dedicated cleaner.

Do not use solvent cleaning liquids as they may cause discoloration.

Folding roller

• If the folding rollers accumulate paper dust or ink from the printed material, it may may make the paper wrinkled or cause troubles such as paper jam. To prevent this, clean the roller regularly using the dedicated cleaner and cloth.
• Using a cloth dampened with dedicated cleaner, strongly rub and wipe off the folding rollers one by one until the cloth no longer picks up any dirt.

Paper feed rubber roller

- If the paper feed rubber roller or the paper separator acquires paper dust or ink from the printed material, the paper folding function will deteriorate, and it may cause paper jam or slippage. To prevent this, clean them using the dedicated cleaner.

6-3 : Expendable supplies

The paper feed rubber rollers and paper separators are consumable products.

Contact your dealer when they need replacing.

	Warning
	When conducting inspections and maintenance service, be sure to remove the electric power plug from the outlet. If not, it may cause injuries or electric shock.

6-4 : Removal and installation, and cleaning of folder roller

Two rollers can be removed and installed without using any tool. Thus, cleaning of the rollers and paper ejection photo sensor can be done easily. As the other two rollers cannot be removed, they should be cleaned while manually revolving them little by little.

[How to remove the folder rollers]

Remove the rear cover and folding tables 1 and 2. Refer to the previous page.)

[1] Move down the roller setting lever to the OFF position.

The roller setting lever is located on both right and left sides.

[2] Slide the upper folder roller to the left.

(The shaft will come off from the left-side hole.)

[3] Remove the roller from the right-side hole.

By the same procedure, remove the lower folder roller.

Caution!

If the roller is not firmly set, it may cause mechanical troubles. If it cannot be fixed, contact your dealer as shown on the back cover.

6-5 : Cleaning of the paper feed, double feed detection, paper ejection photo sensors

[ Cleaning the paper ejection photo sensor ]

Diagram showing that the folder roller is removed (Refer to the figure on page 46.)

If only one sheet of paper is being fed, remove the paper dust on the part of the paper ejection photo sensor indicated by the arrow, using a soft cotton swab.

[ Cleaning the paper feed and double feed detection photo sensors ]

Open the safety cover, and using an air duster, clean [1] the surface of the paper feed photo sensor (black resin face), and [2] the surface of the double feed detection sensor.

(Instead of an air duster, a damp, but not dripping, cotton swab or similar implement may be used.)

Caution!

If using a cotton swab to clean the sensors, ensure that no cotton lint is left behind.

Insufficient cleaning may cause the paper feed to stop, or an error to occur after only the first sheet of paper is fed.

Only turn the machine on when the sensor has fully dried after cleaning.

6-6 : Removal and installation of paper separator, paper feed rubber roller, brake rubber

When replacing the paper feed rubber roller and paper separator, remove them in the following manner.
