Did it work prior to replacing the ribbon? If yes, then perhaps remove the ribbon and replace again. See page 19 of the manual here: https://site.xavier.edu/polt/typewriters/RoyalKMM.pdf

YouTube also has tutorials for how to thread these. (Also search for the No. 10, KH, KHM, HH, Empress, FP, etc. which also used the same general ribbon spools and set up if you can't find a KHM.) I can*t tell 100% from the photo, but the ribbon looks like it's spooling on clockwise on the right (and vice-versa for the left) and you want it the other way.

Is it not advancing regardless of which direction you have the ribbon going? Usually just one side is not working. You can use this fact to compare the typewriter bilaterally. Watch what's going on with the side that does work and compare it with the side the doesn't. What's wrong on the non-working side?

Often times the spindle on one or both sides is frozen up with dried up grease, oil, dirt, or dust. A small quirt of mineral spirits or lacquer thinner (or other degreaser) will free it up. (Here we use the mantra, a typewriter isn't really "broken" unless it's clean and broken.)

Royal KMM FPE HH KH 10 T1 B64 Typewriter Ribbon Install Rewind Respool Replace by [[Phoenix Typewriter]]

The spools for the standard Royal typewriters (KMM, FPE, HH, KH, etc) have a custom metal mechanism for their auto-reverse. The spools are known as the T1 (which is the same as General Ribbon part # T1-77B , T1-77BR, and Nu-Kote B64.) If winding on universal ribbon onto them, remove the eyelette which isn't needed and may interfere with the auto reverse.

The function of the mechanism is fairly similar to that of the Remington, but the mechanism is on the spool itself rather than on the spindle.

If necessary, Ribbons Unlimited carries these metal spools: https://www.ribbonsunlimited.com/6N064-Royal-Standard-Electric-Ribbon-64-p/6n064.htm

Royal HH & FP typewriter shipping help by [[Typewriter Justice]]

Advice for how to package a heavy standard typewriter for shipping. Two heavy rubberbands to hold the margin release buttons to protect the escapement. Then plastic wrap to keep the carriage from moving during shipment. Then protection for the knobs and carriage return levers put into a first box. Then packing peanuts in a second box, fill to completely full and tape closed.

Given my current r/typewriter flair ("typewriters + card index = magic"), I couldn't help but appreciate that Lucas Dul features a 3x5" card index (aka database) of typewriter typefaces in a recent video on the 1896 Williams 3 typewriter: https://youtu.be/T1zzXwB3Xh8?si=K4FeiS-V_aev9_SZ&t=506. Those who have been following along on the typeface front will recognize some of the samples from this small index having been featured in a video on typewriter typefaces at https://www.youtube.com/watch?v=scrguKgDNIY.

I'm reminded of a similar card index (or Zettelkasten if you speak German) database of type I saw last year via the Letterform Archive article at Schriftenkartei [Typeface Index], 1958–1971 and a related Flickr version of it at https://www.flickr.com/photos/letterformarchive/albums/72177720310834741/

Lest you think these sorts of analog office pairings are completely obsolete, I feel compelled to mention that I've recently noticed that Pam Beasley's character had both an IBM typewriter and a metal 1970s/80s era two drawer metal card file behind her desk in the TV series The Office (NBC, 2005-2013).

If typewriters and card indexes are your sort of thing, I've got a small personal collection as well as some research and writing about them which can be found at https://boffosocko.com/research/zettelkasten-commonplace-books-and-note-taking-collection/#Boxes

If you follow my collections and work, you know I'm not beyond pairing up a nice typewriter with a card index (or two).

Nabokov began teaching at Cornell in 1948 and must have been relatively financially well-off enough to afford the roughly $95 ($1,248 in 2024 dollars) for a brand new Royal Quiet De Luxe typewriter.

The typewriter is pictured at the top of the article in a photo from a 1958 photo shoot. Presumably he bought it contemporaneously, though may have gotten it used after its release in 1949. The model changed in mid-1950.

This photo, similar to others in the Carl Mydans series for LIFE Magazine is surely from his September 1958 photo series, though I couldn't find an original from the LIFE archive.

Nabokov, reading off of index cards in his zettelkasten, dictates to his wife Vera who is typing on what appears to be a 1949 or 1950 Henry Dreyfuss Royal Quiet De Luxe typewriter.

Notice metal strip on the back of the typewriter with small rectangular blocks. This is the Royal's tabulator set up which distinguishes the Quiet De Luxe model from the Arrow model.

The body styling of this typewriter changed in 1950 from Dreyfuss' original 1948 design. Because it's light gray it has to be from '49 or '50 as the '48 original was a black body with dark gray highlights and didn't have chrome across the front as this one does in an alternate angle.

Notice the chrome on the front of the machine which is sitting in its bottom case shell.
