OKI Printer Job Stuck in Queue? Here's How to Clear It

Clear a frozen print queue on your OKI printer in a few minutes, starting with the quickest fix and working up to the deeper ones.

You hit Print, nothing comes out, and the document just sits in the queue with a status like "Printing," "Spooling," or "Error - Printing." Try to print something else and it lines up behind the stuck job. That's how print queues work: jobs go out one at a time, so a single frozen job holds up everything after it.

The good news is that a stuck job almost never means a broken printer. It usually comes down to a job the computer can't finish handing off, a Windows service that has stalled, or the computer losing track of where the printer is on your network. The fixes below go from quickest to most thorough. Work through them in order and stop as soon as your printer starts printing again.

Why Print Jobs Get Stuck in the OKI Queue

Most stuck jobs trace back to one of these:

• A corrupted or oversized job. A damaged file or a very large one (think a 200-page PDF full of images) can stall while it's being processed and block everything behind it.
• A stalled Print Spooler. On Windows, the Print Spooler service holds jobs and passes them to the printer. If it hangs, jobs pile up and won't cancel.
• The printer's IP address changed. After a power outage or router restart, your OKI may pick up a new address. Windows keeps sending jobs to the old one, so they sit in the queue with nowhere to go.
• A WSD port connection problem. OKI notes that when the printer is in sleep mode, printing may fail over a WSD port. Jobs go in but don't come out.
• The queue is paused or set to offline. A checked "Pause Printing" or "Use Printer Offline" option will hold every job.
• A paper jam, empty tray, or open cover. The printer stops accepting data until the problem is cleared.
• An outdated or mismatched driver. This is especially common right after a Windows update.

Fix 1: Check the OKI Printer for Errors

Before you change anything on your computer, walk over to the printer and look at the display or status lights.

1. Read the display. Messages about a jam, an open cover, low toner, or an empty tray will stop printing cold. Clear the issue and the queued job will often print on its own.
2. Make sure the printer is online. On models with an ON LINE button, the printer won't accept jobs while it's offline. Press the button so the printer shows it's ready.
3. Wake it up. If the printer is in sleep or power save mode, press any button on the control panel and give it a moment to warm up.

If the printer shows no error and the job still won't budge, move on to Fix 2.

Fix 2: Cancel the Stuck Job on the OKI Control Panel

If the printer's display shows "Processing" or "Data Present," the job has already reached the printer's memory. Deleting it on your computer won't clear it, so cancel it on the printer instead. The exact buttons vary by model, but the process looks like this:

OKI printers with a CANCEL button (for example, the C824, C834, and C844):

1. Press CANCEL on the control panel.
2. When the confirmation screen appears, select Yes.
3. Press ENTER (or OK on some models) to confirm.

Act quickly on the confirmation screen. On the C800-series models, if you don't respond within 3 minutes the screen closes and printing carries on.

OKI multifunction printers with a touch screen (such as the MC-series):

1. Open the job list on the control panel.
2. Select the stuck job.
3. Delete it. To stop a job that's currently printing, press STOP.

Worth knowing: Pages the printer has already prepared for printing can't be canceled, so a few sheets may still come out after you cancel. If the display has said "Printing" for a long time and nothing is happening, delete the job from your computer as well (Fix 3).

Fix 3: Clear the Print Queue on Windows or Mac

On Windows 11

1. Open Settings > Bluetooth & devices > Printers & scanners.
2. Click your OKI printer, then choose Open print queue.
3. Right-click the stuck job and select Cancel. To clear everything at once, open the Printer menu at the top of the queue window and choose Cancel All Documents.
4. While you're in that Printer menu, make sure Pause Printing and Use Printer Offline are both unchecked.

On Windows 10

Go to Settings > Devices > Printers & scanners, select your OKI printer, click Open queue, and cancel the job the same way. Keep in mind that Microsoft ended support for Windows 10 on October 14, 2025, so it no longer gets security or bug-fix updates.

On a Mac

1. Open System Settings > Printers & Scanners (called System Preferences on older versions of macOS).
2. Select your OKI printer and click Printer Queue.
3. Select the stuck job and click the delete button (the X) next to it.
4. If the queue shows the printer as paused, click Resume.

If a job says "Deleting" and just sits there, or it comes back after you cancel it, Windows users should go straight to Fix 4.

Fix 4: Restart the Print Spooler and Clear Stuck Files

The Print Spooler is the Windows service that stores print jobs and sends them to your printer one at a time. When it freezes, jobs get stuck in "Deleting" and won't go away. A full reset clears them out for good.

1. Press Windows key + R, type services.msc, and press Enter.
2. Scroll down to Print Spooler, right-click it, and choose Stop. Leave this window open.
3. Press Windows key + R again, type C:\Windows\System32\spool\PRINTERS, and press Enter. Click Continue if Windows asks for administrator permission.
4. Delete every file inside that folder. Don't delete the PRINTERS folder itself, just what's inside it.
5. Go back to the Services window, right-click Print Spooler, and choose Start.

Open your print queue again. It should be empty. Send a one-page test print before re-sending that big document.

Heads-up: This wipes out every waiting job on the computer, not just the stuck one, so you'll need to resend anything else you had in the queue. If simply restarting the spooler (right-click > Restart) fixes it, you can skip the file-deleting step.

On a Mac, the closest equivalent is Reset printing system. In Printers & Scanners, hold Control, click in the printer list, and choose Reset printing system. Use this as a last resort: it removes every printer from your Mac, so you'll need to add your OKI back afterward.

Fix 5: Restart Your OKI Printer and Computer

A proper restart clears leftover data in the printer's memory and gives both devices a clean connection.

1. Turn off the OKI printer with its power switch.
2. Unplug the power cord and wait at least 60 seconds.
3. Plug it back in and turn it on. Wait until it finishes warming up and shows it's ready.
4. On your computer, save your work and restart it. On Windows, that's Start > Power > Restart. On a Mac, it's Apple menu > Restart.
5. Try a one-page test print.

Restart the printer first, then the computer. That way the computer reconnects to a printer that's already fully awake.

Fix 6: Make Sure Windows Is Sending Jobs to the Right Place

If your OKI is connected over your network (Ethernet or Wi-Fi) and jobs keep piling up even after the fixes above, your computer may be sending them to the wrong address. Windows can still show the printer as "Ready" when this happens, which is why it's so confusing.

Step 1: Find your printer's current IP address.
Print a configuration or network information page from the OKI control panel. On many models it's under an Information or Configuration menu, but the exact menu names depend on your model. Write down the IPv4 address.

Step 2: Check which port the driver uses.

1. Open Control Panel > Devices and Printers (or on Windows 11, Settings > Bluetooth & devices > Printers & scanners > your printer > Printer properties).
2. Open the Ports tab and see which port is checked.

Step 3: Fix the port if needed.

• If the port is WSD: OKI notes that printing over a WSD port may not work when the printer is asleep, and it recommends switching to a Standard TCP/IP port. Click Add Port, choose Standard TCP/IP Port, click New Port, and enter the printer's IP address.
• If it's already a TCP/IP port but the IP address doesn't match: your printer picked up a new address, most likely after a router restart or a power outage. Point the port to the new IP address, or create a new Standard TCP/IP port for it. For a Raw connection, the port number is normally 9100.

To stop this from happening again, give the printer a reserved (static) IP address in your router's settings. That way, the address stays the same after every power outage.

Fix 7: Update or Reinstall the OKI Printer Driver

If jobs still freeze, especially right after a Windows or macOS update, the driver may be out of date or damaged.

1. Remove the OKI printer from Printers & scanners.
2. Download the latest driver for your exact model from OKI's official support site. OKI still lists drivers for existing printers there, even though it no longer sells printer hardware in the US.
3. Install the driver, add the printer again, and send a test page.

Choose the driver that matches your printer's language (PCL or PostScript, for example), and don't reuse a driver from a different model. For the full walkthrough, see our OKI printer driver guide.

How to Keep Print Jobs from Getting Stuck

• Reserve an IP address for your OKI printer in your router so its address never changes behind your back.
• Use a Standard TCP/IP port rather than WSD for network printers.
• Split up very large jobs. Printing a huge, image-heavy PDF in smaller page ranges puts less strain on both the spooler and the printer's memory.
• Don't keep hitting Print. If a job doesn't come out, check the queue before you send it again. Duplicate jobs just make the pile bigger.
• Keep drivers and firmware current, especially after a major operating system update.
• Clear jams and error messages right away so the printer doesn't sit on half-finished jobs.
