Ryobi Tools, Printers, and the Mistakes I Made: 7 FAQs That Will Save You Money

2026-08-10 · By Jane Smith

These are the questions I get asked after I talk about ordering equipment and supplies for a print shop. I have personally made (and documented) eleven significant mistakes, totaling roughly $18,000 in wasted budget. That number still stings. I handle procurement and maintenance now, and my job is to make sure you don't repeat those exact mistakes.

The tools in our shop are mostly Ryobi because the value-over-price math works for us. The printers and 3D printers are less brand-specific. What follows is the list I keep printed on the wall. I updated it in January 2025, after one more ugly printhead clog.

Quick list:

  • What should I actually read in the Ryobi 6500 watt generator manual?
  • Is the Ryobi 10 inch drill press worth it for a small shop?
  • When does a multi extruder 3d printer actually pay for itself?
  • Can you trust target printer ink?
  • How do I clean inkjet printer heads without ruining them?
  • Why do printheads clog in a workshop?
  • Is the lowest price ever the right price?
The most expensive thing is not the machine. It is the assumption that a lower price has no other consequences.

What should I actually read in the Ryobi 6500 watt generator manual?

Most people open the Ryobi 6500 watt generator manual, find the start button, and close it. Don't. The important pages are the break-in oil change (usually within the first 25 hours), the grounding requirements, and the storage procedure. The manual for my 6500-watt unit explains which outlets are protected by which breaker. I ignored those pages once, in March 2022, when I used my generator to power a mobile print trailer during a trade show. It shut down halfway through an afternoon because the oil level was low. The service call and lost event work cost roughly $650. The manual says to check the oil every shift. The manual was right.

Is the Ryobi 10 inch drill press worth it for a small shop?

For making jigs, mounting sign hardware, or drilling through acrylic, yes. I paid about $230 for mine in June 2024. That is not a production floor press, but I don't need a production floor press. The depth stop is consistent enough for fabrication, and the table adjusts without five tools and a prayer. To be fair, I could have saved $120 on a no-name press. I did that in 2018. The runout was visible and the first batch of mounting brackets had holes about half a millimeter off. Scrap cost: $240. The $120 I saved did not cover the first wasted job. The Ryobi 10 inch drill press is not exotic, but it's predictable. For a small shop, predictability is the feature.

When does a multi extruder 3d printer actually pay off?

A multi extruder 3d printer pays off when supports are eating your labor hours. If you print a part with steep overhangs every week and spend twenty minutes prying supports out, the second extruder starts to make sense. You can use water-soluble support material, which dissolves instead of tearing your part. It also lets you print a rigid shell and a soft gasket in the same build. But if you only print one material at a time, a second extruder just gives you a second nozzle to clog (surprise, surprise). I have also watched three failed calibration towers because the idle nozzle was heated too long. My rule is simple: below twenty hours a week of post-processing, buy a single extruder and a better deburring tool. Above that, the multi-extruder math changes.

Can you trust target printer ink?

This one is worth answering clearly because people search it every day. Target is not a printer ink manufacturer. When you buy target printer ink at the store, you're usually buying name-brand cartridges sold through a retail shelf. Sometimes you're buying a third-party compatible cartridge. The real test is whether the cartridge matches your printer model exactly, down to the number on the label. A no-name cartridge can look identical and still miss the chip contact. I tested one once, and the printer rejected it after a long pause. The money I saved was small; the printer took four cleaning cycles and still showed banding. Check the model number, check the sealed bag, and keep the receipt.

How do I clean inkjet printer heads without ruining them?

Start with the printer's own cleaning cycle, not a sharp object. Run a nozzle check, then run one cleaning cycle, then wait fifteen minutes. Patience matters more than force. If that doesn't clear the lines, run the cleaning cycle a second time. Only after that should you try manual cleaning. If the printhead is removable, rest it on a shallow tray with the manufacturer's cleaning solution (warm distilled water works for many Epson models) and blot with a lint-free cloth. Never push metal into the nozzle. I wrecked a $180 printhead in 2023 by trying to unclog it with a sewing needle. Note to self: don't do that again. Over-cleaning is also a problem because it empties the ink pad and makes the printer think there is a leak.

Why do printheads clog in a workshop?

This is the question nobody asks until the nozzle check looks like Morse code. A shop that cuts paper, cardboard, or acrylic creates airborne dust. That dust lands on the printhead and mixes with drying ink. Even a clean-looking print room has more floating junk than an office. The cheapest fix is to cover the printer when it's idle. I also aim to keep the room at or above 40 percent humidity, based on the maintenance note in the printer manual. Low humidity makes water-based ink dry faster in the nozzles. It's not a glamorous tip, but it's saved more printheads than any expensive cleaning cartridge I've bought.

Is the lowest price ever the right price?

Sometimes. To be fair, cheapest can be smart when the failure cost is low, like a one-off part that doesn't matter. But for equipment and ink that hit a production deadline, think about total cost. The price tag is only the first number. Add setup, shipping, rush fees, repair time, wasted material, and the time you spend redoing the job. The cheap quote usually looks better until the second payment arrives in scrap and labor. I saved $80 on a compatible ink lot in 2024, then paid $320 for rush replacement and cleaning supplies when the prints came out banded. The equation was not close. Bottom line: a lower price is a tool, not a strategy.
