The 31-Pin 40cm Head Cable is a replacement flat flexible cable (FFC) for Allwin E-series eco-solvent and UV eco-solvent wide-format printers using the Epson DX5 printhead. Compatible with the Allwin E-160UV Roll, E-180, E-180UV, E-320, and E-320UV printers, this cable connects the DX5 printhead to the printer's carriage control board, transmitting nozzle firing signals across the DX5's 1,440-nozzle array. Specs: 31 pins, 400mm (40cm) length, 1.0mm pitch, same-direction connectors. The Epson DX5 requires two (2) of these cables per printhead — replace both at every head installation.

The E-160, E-180, and E-320 designations indicate printing width (160cm / 63", 180cm / 71", and 320cm / 126" respectively). The UV variants (E-160UV, E-180UV, E-320UV) add UV curing capability to the same chassis for UV-reactive ink applications. All models in this range use the same DX5 31-pin cable interface, making this listing the correct cable for the full Allwin E-series DX5 platform. About the Epson DX5 31-Pin Cable The Epson DX5 is the second generation of Epson's MicroPiezo wide-format printhead, featuring 1,440 nozzles (8 channels × 180 nozzles) and a 31-pin flat cable interface — distinguishing it from the DX4's 21-pin cable. The 31-pin DX5 cable in the 40cm length is the standard cable for mid-to-large format Chinese-branded printers in the Allwin E-series, Zhongye, Human, Xuli, and Aifa platforms. Connector direction matters: DX5 cables are produced in same-direction (A-type) and reverse-direction (B-type) configurations — this listing is the same-direction variant (1.0×31P×400mm-A), which is the correct type for Allwin E-series printers. Using the wrong direction cable will prevent correct seating at one end. DX5 vs DX4 Cable — Key Difference Printhead Cable Pins Cables per Head Notes Epson DX5 (this listing) 31 pins 2 Allwin E-series, Zhongye, Human, Xuli etc. Epson DX4 21 pins 2 Roland SJ/VP/SP, Mimaki JV3/JV4, Mutoh older series Why Data Cables Fail The DX5 data cable flexes with the carriage on every print pass — thousands of cycles per day on high-volume eco-solvent production printers. Micro-fractures develop in the conductor traces at flex and bend points, causing intermittent or permanent signal loss on specific pins. On the Allwin E-series with 2 cables per head, leaving one worn cable in place after a head swap produces the same nozzle drop-out and banding as a full cable failure — and is easily misdiagnosed as a defective printhead. Replace both cables at every head installation. Common symptoms of worn DX5 cables include: • Missing nozzle rows or colour channels on a nozzle check • Regular horizontal banding in output • Colour channels dropping out while others fire normally • Problems appearing immediately after a new printhead is installed DX5 Installation Checklist — Allwin E-Series • Head data cables (this listing) — both cables, never reuse • Dampers — replace all head dampers for the position being swapped • Capping station — degraded cap causes drying on new head during idle • Wiper blade — worn wiper deposits debris on new nozzle face during maintenance Why Buy from Digiprint USA • In stock in Doral, Miami FL — same day shipping before 2PM EST • 31-pin 40cm same-direction — the correct Allwin E-series specification • Ideal for Latin American Allwin operators and eco-solvent print shops using Miami freight forwarders View our full range of printhead data cables and printer spare parts stocked by Digiprint USA. Frequently Asked Questions What is the difference between DX5 and DX4 cables?The Epson DX5 uses a 31-pin FFC cable; the DX4 uses a 21-pin FFC cable. They are not interchangeable. The Allwin E-series printers listed here all use the DX5 printhead and therefore require this 31-pin cable. If your printer uses the DX4 head (common on Roland SJ/SP/VP series, Mimaki JV3/JV4, and older Mutoh models), see our separate DX4 21-pin cable listing. What does "same direction" mean for this cable?FFC cables are made in two connector orientation variants: same direction (both connectors face the same way — also called A-type) and reverse direction (connectors face opposite ways — B-type). The Allwin E-series requires the same-direction (A-type) cable. Using a reverse-direction cable will prevent correct seating at one end of the connector. This listing is the correct same-direction variant for Allwin E-series printers. Is this cable compatible with other DX5-based printers like Zhongye or Human?The 31-pin 40cm same-direction DX5 cable is widely used across Chinese-branded wide-format eco-solvent printers including Allwin, Zhongye, Human, Xuli, Aifa, Witcolor, and others. However, cable length requirements vary by printer model — 40cm is correct for the Allwin E-series listed here. Other brands or models may require 28cm, 35cm, or 55cm lengths. Contact us with your specific printer model to confirm the correct length.
