Buying Used B6000 Equipment on Craigslist
Craigslist is still one of the most active places to find used industrial and commercial B6000 units, and it's also one of the most dangerous ways to spend money if you don't know what you're doing. I've been through enough of these transactions to know where people get burned, so here's what actually happens when you go looking. You'll find mostly two types of listings: people upgrading their equipment and cleaning out their offices, and middlemen who have no idea what they're selling. The first category usually has honest descriptions with photos that match the actual item. The second category is where you'll see listings with stock photos from the manufacturer's website and prices that are already padded by 30-40%. Look for sellers who post genuine photos taken with a phone, preferably showing wear patterns that match the description. If every surface looks pristine in the listing but the price is suspiciously low, something is almost certainly wrong. When you go see the unit, bring a multimeter and a power cable that fits. Most B6000 equipment draws significant current and has known issues with power supply boards that fail intermittently. Test it under load if you can get the seller to leave it plugged in for at least twenty minutes before you arrive. Cold startups are deceptive - components that have thermal failures often work fine until they warm up. I once bought a B6000 that appeared completely functional during a thirty-second demo, then developed a grinding noise after ten minutes of operation. The bearing on the primary drive was shot. The seller swore it was "just settling in." It wasn't. That unit ended up costing me about four hundred dollars in parts I wouldn't have bought if I'd run it longer during the test.
The most frequent issue with used B6000 units is worn calibration rollers. These degrade over time and cause consistent quality problems that are easy to mistake for a deeper failure. A full recalibration after installation usually fixes most symptoms, but you need the proper calibration procedure from the service manual. Don't skip this step assuming the previous owner handled it - they didn't. Second, check the firmware version. Some B6000 revisions have known bugs that were patched in later releases, and older firmware combined with worn mechanical parts creates problems that don't show up during a quick test. You'll discover them three weeks later when the unit is sitting in your shop doing nothing useful. Also worth noting: shipping a B6000 is not trivial. These units weigh between eighty and one hundred twenty pounds depending on configuration, and they contain sensitive alignment components that can shift during transport. I've seen units arrive with laser alignment off because the seller used a standard box courier instead of a freight service with liftgate and white-glove handling. The difference in cost is usually two hundred dollars, and the difference in headache is everything.
Pricing and negotiation
As of right now, a used B6000 in good working condition typically lists between eight hundred and two thousand five hundred dollars on Craigslist, with the lower end being units that need work and the higher end being recent models with minimal runtime. Negotiate down by pointing out specific wear items you'll need to replace - calibration rollers, fuser assemblies, power supplies are all common replacements that cost two to six hundred dollars new. Use those numbers as leverage. Most private sellers listed prices that are already inflated, and they expect some haggling, especially when you're offering to pick up the unit yourself. If the seller is asking above two thousand for a used unit with unknown history, walk away. There are plenty of other listings, and refurbished units from authorized dealers sometimes come with warranties that make the slightly higher price worth it.

Alternatives to consider
Not every B6000 purchase belongs on Craigslist. If you need the unit for production work where downtime costs money, look at surplus equipment dealers or authorized refurbished resellers instead. They inspect and test the units before selling them, and most offer at least a ninety-day warranty. Craigslist works fine for hobbyists, research projects, or situations where you have the time and tools to diagnose problems yourself. It doesn't work well when you need reliability on day one.
