Mimaki E301184 Encoder Scale Buying Guide: How to Confirm the Correct Linear Scale Before Ordering
The linear scale is the thin patterned strip read by the encoder sensor. Editorial scenes are AI-generated from the store’s real product photographs; they illustrate off-machine inspection, not an installation or a specification measurement.
Is E301184 the right scale to order?
Confirm the complete part reference against your exact printer model and serial number, then match the strip specification and both mounting ends. A similar-looking coil, a shared printer brand or the same nominal resolution is not enough to establish fit.
This Mimaki E301184 encoder scale buying guide is for printer owners, technicians and purchasing teams replacing an identified linear scale. It helps turn an incomplete request such as “Mimaki encoder strip” into an order that a supplier can actually check.
The current UVINKPRO MP-E301184 listing is described as a compatible replacement encoder scale. Its package description covers one scale; a sensor, cable, bracket or spring should not be assumed to come with it.
First Decide Whether You Need the Strip or the Sensor
Linear encoder scale
Match the part code, optical specification, dimensions and mounting ends. This is the part category covered by the E301184 listing.
Encoder sensor assembly
Identify its own part number, connector and mounting arrangement. Ordering a scale does not replace a faulty reader.
Check the system first
Record the full error and when it occurs. Ask a technician to distinguish scale damage from reader alignment, wiring or mechanical issues.
Mimaki’s SWJ-320S service documentation treats the scale and encoder sensor as separate components and checks their relative position. This explains why the names cannot be used interchangeably; that manual is not evidence that E301184 fits every SWJ-320 version. Manufacturer service reference, sensor positioning.
Read the Entire Code, Including Prefixes and Suffixes
The store’s product gallery includes package photographs marked MP-E301184 and E301184-00-4400. Preserve the full string in your inquiry instead of dropping the prefix, revision-like suffix or trailing number.
- Photograph the old package label, service record or part identification if available.
- Send the printer nameplate with its full model suffix and serial number.
- Ask the supplier to map the quoted replacement to that exact machine or documented service part.
- If a different or superseding code is proposed, request the cross-reference before payment.
A product-gallery label is useful identification evidence. It does not independently prove the current shipment’s dimensions, revision or manufacturer origin. The listing’s current replacement description should guide the purchase; do not treat older image filenames or packaging photographs as an authenticity state.
Compare Both Ends, Not Just the Coiled Shape
The end detail shows what to photograph for a fitment inquiry. Use actual stock and old-part photographs to compare hole count, spacing and end shape.
A rolled-up scale conceals most of the information needed to compare replacements. The reference image shows a terminal with two holes, but a buyer still needs clear views of both ends and the actual mounting arrangement.
| Check | Request or record | Buying mistake to avoid |
|---|---|---|
| Length | Overall length and usable reading length, with units and measurement endpoints. | Using printer print width as the required strip length. |
| Width | Actual strip width from a specification or careful measurement of an accessible spare. | Judging width from a listing thumbnail. |
| Optical pattern | Required resolution and the supplier’s definition of LPI or DPI. | Choosing a higher number as an upgrade. |
| End geometry | Both ends, hole spacing, slots and any separate holders or tensioning parts. | Assuming matching length makes the ends interchangeable. |
| Reading position | The machine’s scale path, orientation and reader arrangement from service information. | Copying an installation from a different printer. |
If a quote contains “150 DPI,” “180 LPI” or “4400,” ask what each value describes and which units apply. A printed trailing number should not replace a complete specification. The current store description does not supply a verified dimensional drawing or complete machine fit list.
Which Printer Details Make Compatibility Checkable?
Include the complete nameplate model, not an abbreviation such as “SWJ320” or simply “Mimaki UV.” Model suffixes and service revisions matter when comparing parts. If your inquiry concerns a UJV55-320, SWJ-320EA or SIJ-320UV, send that exact identification and the old part reference; this guide does not certify an unconditional fit list for those machines.
If the old label is missing, use the machine’s parts documentation or a technician’s confirmed part reference. Provide clear photographs of the existing strip ends and its holders where safely accessible. An error screenshot is helpful diagnostic context, but it cannot identify length or optical resolution.
The printer’s ink system can help identify the machine configuration. It does not make an encoder scale an ink-contact component, and ink type alone cannot establish scale compatibility. There are no ink-tube or damper connectors to match on the bare strip.
An Encoder Error Does Not Automatically Mean a New Scale
Illustrated inspection of a detached part. The image does not show a cleaning procedure or resolve the optical line count.
Visible tears, creases, damaged mounting ends or scratches across the reading area warrant technical assessment before reuse. If the strip appears intact, record whether the fault occurs at startup, during carriage travel or after maintenance instead of buying on symptoms alone.
Mimaki’s SWJ-320S diagnostic reference checks several possibilities, including twisting, spacing, unwanted contact, scale damage and loose fasteners. These are examples of a system-level check, not instructions to adjust your machine using another model’s settings. Manufacturer service reference, encoder diagnostics.
Cleaning guidance must match the printer and scale material. For example, Mimaki’s published JV400LX/JV400SUV FAQ excludes ink-specific cleaning solution from its scale-cleaning procedure. That model-specific advice should not be copied as a universal E301184 cleaning recipe. Mimaki FAQ and applicable models.
Before Ordering: Send One Complete Fitment Record
Copy this checklist into your inquiry:
- Printer model, suffix and serial number; nameplate photo.
- Old part code and full package-label photo, including any suffix.
- Both strip ends, overall appearance and accessible holder photos.
- Required length, width and optical specification, with the source of those values.
- Exact error message, when it occurs and checks already completed.
- Required quantity, destination and whether separate mounting parts are needed.
Ask for a written confirmation of the offered reference, dimensions, optical specification and included parts. Request current stock photographs when the old part and catalog image differ. Confirm dispatch timing and return conditions for an uninstalled mismatch in your quote before arranging the repair.

Have the Old Part Photos Ready?
Send the fitment record through the E301184 product page before placing an uncertain order. If the scale has not been identified as the replacement needed, start with the encoder strip inspection and replacement guide and your machine’s service documentation.
E301184 Encoder Scale Buying FAQ
Are E301184 and MP-E301184 the same ordering reference?
Both forms appear in the store’s reference photographs. Send the complete code shown on your old part or package and ask the supplier to confirm the offered item; do not assume every prefix or suffix can be ignored.
Does the scale include an encoder sensor?
The current product description specifies one replacement scale. A reader, cable, bracket or spring is a separate requirement unless the quote explicitly includes it.
Can another strip with the same LPI replace E301184?
Matching nominal resolution alone is insufficient. Length, width, optical characteristics, end geometry and the machine’s mounting requirements must also be checked.
Will a new scale fix carriage errors or shifted printing?
Only if the scale is the relevant cause and the replacement is correctly fitted. Reader alignment, wiring and mechanical conditions may require separate diagnosis.
What should I check when the replacement arrives?
Before installation, compare the agreed reference, ends and specifications, photograph the received item and look for transit damage. Keep the packaging and pause installation if anything differs from the confirmed order.
