6-inch dye-sublimation

DNP DS620A drivers, manual & firmware

DNP's most widely deployed 6-inch printer for photo booths, event photography and retail printing. Printer designation in DNP documentation is DP-DS620 Series.

Print sizes

3.5×5, 4×6, 5×7, 6×8 and 6×9. Panoramic 6×14 and 6×20 prints are produced from standard 6×8 media — no specialty paper — but require DS620A firmware v1.52 or later together with WCM Plus or Hot Folder Print v2.2 or later. Standard and enlargement print trays cannot be used for panoramic output.

Official DNP resources

DS620A Windows and Mac printer drivers are published on DNP's driver index alongside the drivers for its other current printers. Open the index above and look for the DS620A entries.

High-capacity event printer

DNP DS-RX1HS drivers, manual & firmware

Built for long events where minimising roll changes matters. Note that DS-RX1HS and the earlier DS-RX1 share a driver but not media — once a DS-RX1 is upgraded to HS firmware it requires RX1HS media and the change cannot be reversed.

Compact 4-inch dye-sublimation

DNP QW410 drivers, manual & firmware

DNP's smallest professional printer, designed for mobile booths, roaming event work and ID systems. Printer designation in DNP documentation is DP-QW410.

Print sizes

On 4-inch media: 4×3, 4×4, 4×4.5 and 4×6. On 4.5-inch media: 4.5×3, 4.5×4, 4.5×4.5, 4.5×6 and 4.5×8. The paper holder uses removable spacers — remove them when switching to 4.5-inch paper. Do not mix 4-inch and 4.5-inch media in the same printer, as it can produce visible lines on prints.

8-inch dye-sublimation

DNP DS820A drivers, manual & firmware

DNP's 8-inch printer for portrait studios, schools, attractions and larger print products. Printer designation in DNP documentation is DP-DS820 Series. Its user guide is shared with the DS620A.

Print sizes

8×4, 8×5, 8×6, 8×8, 8×10, 8×12, plus A5 and A4 formats. The paper holders convert between 8-inch and A4 width by pulling the knob and rotating the flange — both holders must be set to the same width. Unlike the DS620A, the DS820A will not print with the scrap box removed.

Paper jam

Release the opening lever and pull out the mechanism, remove the ribbon cassette, then rewind the paper onto the spool against the paper path and draw it forward out of the printer using light pressure only. Cut away any wrinkled or partly printed section squarely with scissors before reloading — an uneven cut will jam again. If a jam will not free without force, stop and contact DNP; forcing it can damage the cutter or the head.

Torn or caught ribbon

Pull the ribbon out and cut it, then carefully remove the remaining ribbon from inside the printer. Rejoin the ribbon with tape, rotate the take-up roller until the taped section is no longer visible, and refit the cassette. Any ribbon fragments left inside will affect print quality — clean the platen roller if you see marks afterwards.

Stopped mid-cut, or power lost while printing

Set the power switch to standby and back on. The jam releases, the cutter returns to its rest position, and any partly printed paper is cut into scrap and ejected. Check nothing remains inside before reloading. On the DS620A and DS820A you cannot pull out the mechanism until you have cycled the power.

Repeating lines or marks on prints

Marks recurring at a regular interval — roughly every 50 mm on the DS620A and DS820A, roughly every 38 mm on the QW410 — or a dirty white side of the print indicate the platen roller needs cleaning with ethyl alcohol on soft gauze. Uneven density or gaps instead point to the thermal head. Let the head cool first; it stays hot after printing.

Ribbon alarm or reduced colour density

DNP ribbons carry an IC chip used for colour adjustment, media recognition and print counting. If the printer cannot read the chip it sounds an alarm and deliberately lowers ink density to protect the printer. This is the usual cause of dull output on non-genuine media.

Before you ship a printer for service

DNP requires the original packing materials and the print head protective sheet. Remove media, cables and the paper tray and pack them separately, empty the scrap or trash box, and tape the front cover closed. Incorrect packing is a common cause of transit damage that is not covered.

Before you call DNP

Have these ready — it shortens the call considerably:

The printer model and serial number. The current firmware version and driver version, both readable with DNP's Status Display Tool. The exact LED pattern you are seeing. The media size and type loaded, and whether the fault occurs with a fresh roll. The operating system and version, and whether printing goes through Hot Folder Print, WCM Plus or a booth application.

DNP's customer service team operates from its Concord, North Carolina headquarters, Monday to Friday.

Why we do not link the driver ZIP files directly: DNP places its software behind a licence agreement you must accept before downloading. Linking around that gate would be inappropriate for an authorized dealer, so we link to the DNP page holding the file and name the file for you.

EventPrinters.com is operated by Southtrend Corp., an authorized DNP dealer based in Miami, Florida. Southtrend has worked in professional photo printing since 1996, supplying printers, genuine paper-and-ribbon media and event printing equipment to photo booth operators, event photographers, studios, schools, attractions, retailers and government users across the United States.

We built this page for our own customers, and we maintain it the way we would want a supplier to: every link is opened and re-checked on a fixed schedule, and every specification is taken from DNP's published user guides rather than from retailer listings, which frequently carry stale or transposed figures.

Where a figure could not be verified against a DNP document, we leave it out rather than repeat it. Where a resource covers several models at once, we say which ones it covers.

DNP Imagingcomm America Corporation remains the authoritative source for drivers, firmware, warranty decisions, technical diagnosis and repair. Our role is to get you to the right DNP resource faster, and to keep your printer supplied once it is running.
